Amex Prepaid Card Complaint

Amex Prepaid card department,

General purpose card Adding money Connecticut

I ( tried ) to use the American express serve prepaid mobile app to deposit a check, which they say takes up to 6 days to apply the funds. I assumed it was to ensure the check cleared. What they do n't tell you is that they use a vendor to evaluate whether or not to accept the check. They check I deposited was rejected and even after speaking to a vendor rep I have no idea why. The information is proprietary and they wo n't tell you why a check was not accepted. They do not provide guidelines of any sort, which means any check can be rejected for any reason. Their excuse is that it is an app and we should n't expect every check to be accepted. The problem is that the American express serve prepaid website and the app do not give any indication that the check will be put through this arbitrary process. this need to be fix I am scared to use their mobile check app fearing that when deposit a check that it will get rejected for no reason
