RBS Citizens Bank Account Or Service Complaint

RBS Citizens Bank account or service department,

Checking account Account opening, closing, or management Pennsylvania

I was charged a $ 20 monthly fee for a checking account and did not realize this until - fees had been charged ( - and - -/-/2015 ). No checks were written for insufficient funds. When I complained I received an email indicating $20000.00 was a minimum balance. I do n't recall being informed of that before and these fees were not levied previously.
