In the dispute notification, we include the card/bank holder's name, which in most cases will match the customer record in Zingfit. If you're not able to locate the customer with the name provided, please try the following steps.
Under Reporting on your Admin page, go to the "Sales by Gateway" report.
Filter your date range to a 3-day timeframe from the original transaction date. For example, if the charge was on January 2nd, you would want to filter it from the 1st to the third.
From those results, you can search using control+f/command+f with the transaction ID provided in this email
