Ridiculous fees!!!!

I have been a standard bank client for about 15 years now and the service is deteriorating and totally unacceptable. My credit card charges are irregular. On contacting the call centre I was advised that there are three charges, a service charge, a finance charge and a cash finance charge. The cash finance charge increases every month and the finance charge was service fee remains roughly consistent. When I complained about it the consultant couldn't answer me. I'm seriously considering moving to another bank, I'm tired of their ****!
