Amex Prepaid Card Complaint

Amex Prepaid card department,

General purpose card Adding money Washington

I had recurring loads set up on my prepaid card account. On - -, I had a scheduled load for $200.00. I went to a restaurant and left a tip. I came home to find an email informing me that the ability to load my account had been terminated for no apparent reason ( the customer service reps refuse to tell me why either ). The $200.00 scheduled load did not go through. The amount in the account was enough to cover my meal, but when the tip posted it left my account with a - $2.00 balance. Since - -, I have attempted to pay the - $2.00 balance multiple times including multiple phone conversations. Serve will not allow me to load my account but consistently sends me warning emails that my account has a negative balance. I want to be able to pay them their $2.00, but they wo n't let me.
