Amex Prepaid Card Complaint

Amex Prepaid card department,

Gift or merchant card California

I enrolled in American Express has premier shipping plan with a fee of - $ so that I do n't need to pay shipping charges. I enrolled in 90 day trial. They are not supposed to charge during the trial but they charged - $ when I called them they said they will refund the fee when I cancel within 90 days. I cancelled my plan within 90 days but they did n't refund my charges. When I called them to cancel they said they will refund in 15 business days and now it is past 15 business days and when I called them again ( I was waiting on the phone for 90 minutes ) they are saying they need to reprocess the refund. I am not sure whether I will really get the refund. There are two problems1. They are not refunding in timely manner ( they already crossed the time they mentioned in terms and conditions ) and I am not sure they will refund me. 2. They are not supposed to charge during the trail but still they charged my account. I spent lot of time to track this and I am looking for compensation for my lost timeMy case number with AME- is # -My order number that contains the Premier shipping charges is -
