Refund Disaster

I am struggling to get my refund processed. Payflex double debited my account. I have lodged several queries and eventually after alot of back and forth they eventually agreed to refund my money, but then they refunded and immediately deducted the same amount again. I have lodged queries, but my ticket keeps getting closed without any resolution. I am deeply disappointed because I have used Payflex several times and didnt have these issues in the past. I always pay on time and now I am being treated like this. There is no phone number to contact anyone, so you are just left in the dark with no assistance.
