E-commerce

A double charge is one of the most stressful issues for a customer. They see two amounts in their account or wallet and want to know if the shop has charged them twice, if there is a duplicate order, or if one of the amounts will disappear.
The chatbot must distinguish between a temporary authorization, a double attempt, a duplicate order, wallet payment, and actual capture. It must quickly transfer cases of confirmed charges or requested refunds.
This guide shows how to handle a double charge error methodically and with empathy.
Summary
Why does the double debit create an urgency?
The customer sees their money blocked or deducted. Even if one of the amounts is a temporary authorization, the felt effect is real: anxiety, loss of trust, and the need for a quick response.
The chatbot must acknowledge this concern and explain the verifications before concluding.
Faced with a double charge, the first response must reassure without minimizing.

Which situations should be distinguished?
A distinction must be made between a bank authorization, a failed payment, two validated orders, a single order charged twice, a wallet displaying two lines, or a pending refund.
Each case requires a different action. The bot must compare the order, the confirmation, and the statement.
What information should be requested?
The bot may request an email, order number, amounts, dates, payment method, bank or wallet, screenshots with sensitive data masked, and confirmation messages.
It must never ask for the full card number, the CVV/cryptogram, or a bank code.
How can the temporary authorization be explained?
An authorization may appear after a payment attempt without a confirmed order. It often disappears after a banking delay, but the bot must check the source before stating this.
If the amount remains debited or if two confirmations exist, it must be escalated.
How do I manage two orders?
If two orders have been created, the chatbot must verify their status, the items, the address, the payment, and the possibility of cancellation before preparation.
The customer must understand whether we are talking about a technical double payment or two genuinely registered purchases.
This distinction also helps to decide whether to quickly cancel a duplicate order, wait for an authorization to disappear, or initiate a refund.
The customer must see that customer support is comparing the proof rather than responding with a generic explanation.
Which flow to follow?
The flow must compare payment and order.
Identify order, email, amounts, dates, payment method, wallet, and captures.
Compare order confirmations, payment attempts, bank statements, and system status.
Distinguish between authorization, actual charge, duplicate order, refund, or failed payment.
Explain the banking delay if a temporary authorization is likely.
Forward confirmed charges, duplicate orders, refunds, disputed wallets, and financial emergencies.
Which messages should be used?
To acknowledge: "I understand your concern, we will compare the payment and the confirmed orders."
For security: "Mask the full card details on any screenshot sent."
For authorization: "This may be a temporary authorization, but I will check the details before concluding."
When to transfer?
The transfer is necessary if two charges are confirmed, if two orders exist, if a refund is requested, if the customer disputes a wallet, or if the amount is significant.
The bot must transmit the order, amounts, dates, payment method, masked screenshots, confirmations, and customer expectations.
Which KPIs should be monitored?
Track double debits, authorizations, double orders, refunds, payment methods involved, resolution times, and satisfaction after correction.
This data shows if a provider or a checkout step is creating too many incidents.
Which mistakes should be avoided?
Avoid saying "it is only an authorization" without proof, asking for sensitive banking data, advising to repay without verifying, or treating the subject as a simple bug.
The chatbot must secure the verification and accelerate the human takeover.
How can Qstomy help?
Qstomy can connect the chatbot to business rules, orders, packaging, support decisions, payments, downloadable products, and escalation procedures to answer clearly, then transfer sensitive cases with an actionable summary.
The chatbot helps the customer move forward without inventing a discount, a package privacy guarantee, a support exception, a double charge refund, or download access that has yet to be confirmed by a reliable source.
