Amex Prepaid Card Complaint

Amex Prepaid card department,

Gift or merchant card Fraud or scam Florida

because I have no bank account, I purchased an American express gift card to pay some bills with. I was not able to use my balance of $320.00 on any of my bills, - I contacted the gift card service center in - on - separate occasions, and spoke with - separate floor supervisors and was repeatedly told that there was nothing wrong with my card. I repeatedly tried to use it online, on phone, and directly speaking with my creditors with no success. - floor supervisor, - - -, at - customer service advised that it is not meant to be used to pay bills. I told them it should be able to be used just like a credit card for any reason. After not being able to get customer service to help me in any way I asked fpr a refund and was told that it would take 20 business days for a refund. It sure seems like a scam to me. I spent good cash money and now am out $320.00 for at least a month. This is not a responsible business practice, and not fair to the individual. Please help me to resolve this absurd practice. I never have similar problems with other major gift cards -. I just want to be fairly treated, and hope you can help me, and others like me. Thank you,
