Regions Bank Account Or Service Complaint

Regions Bank account or service department,

Checking account Problems caused by my funds being low Texas

I opted out of overdraft coverage and have been told that no items would go through and charge me overdraft fees. I was charged - over draft fees this month due to Regions Bank allowing me to overdraft my account. I called and found out that they can only refund $18.00 of the overdraft fees. It seems to me that they want me to keep over drafting to pad their fee income. I would told that my line of credit I have with The bank that if I did overdraft it would pull from my line of credit, I was lied two about both of these items. I believe CFPB should look into Regions Bank handling of overdraft fees, specially why they allow for these lies to happen. Please help, - over draft fees to the bank is nothing but for me on a fixed income it means the difference of my car being paid.
