Useless bank. no customer service

Please do not bank with this useless idiotic company. I have lodged a complaint of ***** and have sent back a dispute form which takes 3 working days to processes. I called back the following week and no response, so I leave it for a while hoping some one will call me back, but nothing. Today I call back and get transferred to at least 6 different departments and no one can help me (general inquiries, ***** department, follow up department etc). I would like to just add, they allow my account to go into arrears with *****, they say they are trying to help me as a customer so they let the money go through. ****ing joke!
