Still no formal response to my complaint

Diners club added a card replacement fee to my account without informing me of the charge. Then they never ever sent a statement or account - now they have added R1500.00 worth of non payment charges to the account.<br> On raising the matter with them, they fail to respond formally - I still have not ever got a statement from them.<br> So I am still sitting with the problem and have no-one to talk to despite informing them of my complaint.<br> On the Hellopeter website they say problem resolved and supply the same help desk number that failed to assist me in first place!<br> Any complaint just gets swallowed in an Amorphous mass of incompetence and poor customer service!
