PayFlex Systems USA review: Payment

I received a letter from PayFlex stating that I was in overpayment status. I sent them documentation of payment. They approved my claim and still put a suspension on my account. I contacted them and they told me even though my overpayment was satisfied there was still a wait period for them to active my card. Now I have a doctors appointment and will have to pay out of pocket and send in receipt's. I will have to call them 20 times and I will get reimbursed in about 3 months. Horrible customer service to deal with. I think my time is valuable and don't need to spend endless hours on the telephone resolving issues caused by their inept staff.
