# Duplicate

Click on the appropriate tab depending on whether the disputed transaction involves a physical product, a digital product/service, or an offline service.

{% tabs %}
{% tab title="Physical" %}
If the dispute involves a physical product, please ensure to submit the following evidence:

* ID of the previous payment that appears to be a duplicate of the disputed payment (if there is a duplicate payment)
* explanation of the difference between the disputed payment and the one that is a duplicate from the customer's point of view
* separate payment receipt or other document relating to the previous payment that clearly identifies it (Please attach this document to a similar document to the disputed payment that proves that there are two separate payments. If possible, please attach a receipt or separate shipping label for the other payment. Provide an appropriate packing list for shipping multiple products.)
* shipping receipt or label for the product of the disputed transaction
* proof of whether or not the customer tried to find a solution with you prior to the dispute
* customer communication information if you communicated with the customer prior to the dispute or if subsequent conversations were used for clarification, such as:
  * PDF or screenshot of the conversation
  * PDF with written report on a telephone call (incl. contact details)
* all documents that refute the reason for contestation, for example screenshots or PDFs with:
  * copies of payment receipts showing that each payment was made separately (if not available, a summary of all individual payments)
  * proof that a refund has already been made
  * proof of withdrawal of the dispute by the cardholder
    {% endtab %}
