Regions Bank Account Or Service Complaint

Regions Bank account or service department,

Checking account Problems caused by my funds being low Florida

On - - our account had $180.00 without anything being in the negative the bank took out $140.00 for Overdraft fees and still never showed a negative. We had - pending items - - which was going to be credit back in a couple days for $180.00. Our account never showed negative, and they never had to cover this item. The bank is telling me they wont refund our money. We feel as if they stole our money. I dont understand how with something pending how they can automatically charge you a OD payment with the item was not yet paid by them. This was a error and it was corrected as well as why are we being charge OD fees when they didnt have to cover anything?
