Payflex does not want to refund me

I placed an order in June 2025 and the first payment went through. I then made payment on the 24 July 2025, Payflex debited me again on the 25th of July 2025. The last payment went through on August. I then sent the email to support and I was asked to provide a bank statement and the order number, which I did sent. They told me that they are investigating the issue from the 2nd of October 2025 till now I have not received my refund nor any feedback. When I send emails asking about feedback they do not respond.
