This issue is ongoing...
I reached out to my credit card company about a charge on my account from Stamps.com. The rep recommended I call the merchant and work out the dispute.
I called the merchant about the charge and other charges on my card stemming back to 2021. The Stamps rep said I could not get a credit. After requesting for a supervisor who never got on the telephone and he instructed the rep to give a refund.
The Stamps.com rep said she could only give me the last three months worth of charges. She typed in some information in the computer and after some time said she was sending the claim over to their escalation department and that they would issue a refund and that I would receive it by the end of the month.
Today, I reach out to my credit card company and after talking with three reps, the last one actually filed the dispute. From what the credit card rep told me, Stamps.com only issued a $12.61 credit.
