Not legal or financial advice. This page is not a substitute for your processor dispute console, card-network reason codes, acquirer playbooks, a licensed attorney, or your judgment. It describes a merchant ritual: use Pingpong to write a dispute description when the claim is currency error, wrong currency charged, or a conversion / FX surprise on the statement. Nothing here coaches cardholders on filing currency disputes or inventing phantom exchange rates.
A dispute lands stamped currency error or conversion complaint. Finance sees a settlement currency and a cardholder billing currency that never match on a statement. Ops wonders if DCC (dynamic currency conversion) or a multi-currency checkout confused the buyer. Support has a chat that says "I was charged in the wrong currency." One model already wrote "clearly a FX scam." The submit button still wants a mapped narrative: which currency was offered, which the buyer selected, the rate disclosure if any, and what settled. That is the moment this page is for.
People searching currency error chargeback response, wrong currency dispute rebuttal, or how merchants respond to FX conversion claims usually get generic international-billing FAQ pages. Useful starting points. This page is narrower. It treats currency error as a merchant evidence narrative: show the currency offered at checkout, the buyer's selection, any DCC or conversion disclosure, and the settlement trail, without hoping tone substitutes for processor receipts.
This is distinct from incorrect amount chargeback response (same-currency overcharge / wrong-dollar claims), from duplicate processing chargeback response (twin settlements), from no authorization chargeback response (auth-trail / consent), and from credit not processed chargeback response (refund already owed). Compelling pack language: compelling evidence for chargebacks. Primary writing ritual: write your dispute description. CASE MAKER letterhead PDF path (first PDF free, then $9/PDF or 5-pack $29 when export ships): win disputes. Hub: dispute cases. Buyer-side pause: before you file a chargeback.
Use Pingpong to write your dispute description. Paste the reason code, order ID, checkout currency offered and selected, settlement currency and amount, any DCC or FX disclosure screenshots you may store, issuer conversion notes if visible, partial credits already issued, customer chats about the currency surprise, and the deadline. Default chain: Grok, then Perplexity, then ChatGPT, then Gemini, then Claude. Later labs challenge soft "they chose USD" claims without a checkout artifact, missing DCC disclosures, and tone that lectures the cardholder. Brand: Pingpong at pingpongit.com. Not getpingpong.ai.

Currency error is a conversion-disclosure social object
The cardholder story is usually: charged in the wrong currency, or the FX rate shocked me. Your story has to be an honest shape: checkout offered currency A, buyer selected A, settlement matches; DCC was offered with a disclosed rate the buyer accepted; issuer conversion after a foreign-currency settle (issuer-side, not merchant padding); a multi-currency cart bug you already credited; or a true wrong-currency capture that should be refunded or rebooked. Network codes and processor labels vary. Read the code on this case. When the stamp is same-currency overcharge, shift to incorrect amount chargeback response.
What usually breaks currency-error replies: asserting "they chose the currency" with no checkout screenshot; uploading a settlement report without the currency code the buyer saw; blaming the issuer for a merchant DCC choice you controlled; mixing an incorrect-amount rant into a currency code; missing the reply window while waiting for bank FX letters; tone that lectures the cardholder about traveling abroad.
Hard line: legitimate merchant defense only. If you truly settled in a currency or at a conversion the buyer never agreed to, refund or rebook and close. Do not invent a currency picker click. No coaching to deny valid currency-error claims.
The merchant ritual before Submit on a currency-error case
Read the reason code and the processor checklist. Gather what you can prove: order ID, currencies offered and selected at checkout, DCC or FX disclosure, settlement currency and amount, issuer conversion notes if available, partial credits, customer chats. Restate the claim in the cardholder's words. Draft a short dispute description that maps proof to either "buyer-selected currency matches settlement" or "difference already credited." Run Pingpong on the draft plus the evidence inventory. Edit. Upload. Submit before the deadline.
Compelling pack language: compelling evidence for chargebacks. Network maps: Visa chargeback reason codes, Mastercard chargeback reason codes. Sibling reasons: incorrect amount chargeback response, no authorization chargeback response, duplicate processing chargeback response, credit not processed chargeback response. Broader first response: respond to a chargeback. Related irreversible-submit habit: Catch AI mistakes before you commit.
How the five-model handoff works on a currency-error response
Example shape: Processor PROCESSOR, reason code CODE (currency error / conversion as labeled), checkout currency OFFERED, buyer selection SELECTED, settlement currency SETTLE_CUR, settlement amount SETTLE_AMT, DCC or FX disclosure LIST, credits already issued LIST, deadline DATE. Write my merchant currency-error dispute description, map each paragraph to the claim on the case, and list evidence to upload versus omit. Flag soft "they chose the currency" claims without a checkout artifact. Do not invent proof I did not list. Do not paste full PAN, CVV, bank passwords, or government IDs you are not allowed to store.
Grok drafts. Perplexity through Claude review in sequence. You leave with a tighter description and a gap list. Architecture: Sequential vs parallel AI. Framing: AI second opinion. Debias: Debias AI.
Letterhead PDF path (and what is live today)
Today Pingpong writes and pressure-tests the dispute description and checklist you paste into your processor. The CASE MAKER lander for a letterhead evidence pack outline is win disputes: first PDF free, then $9/PDF or 5-pack $29 when export ships. One-click PDF export is not a live product button today.

Existing API orientation: developer docs.
When to skip
Skip for pocket-change accepts, counsel-owned cases, and clear wrong-currency captures you already know you should refund. Save the free eligible review for mid-ticket cases where offered versus settled currencies need a clean map, or your first draft lectures the cardholder instead of showing the currency picker.
