Synchrony Financial Credit Card Complaint

Synchrony Financial Credit card department,

Texas

I filed a complaint against Synchrony bank for not refunding an over balance on my credit card. They finally sent the check but it was n't until after I filed a complaint and got them to agree to send it. Because I filed a complaint they turned around and put a stop payment on the check costing me a $20.00 bank fee for them sending me a check and then stoping payment on it. They now claim that I have to rerequest another check but they will just put a stop payment on it again, thus harrassing me and punishing me for making a complaint against their institution.
