Beginning of the end for Edgars

I opened my account with Edgars more than 40 years ago. Since Norman Drieselmann took it over, it has been one major disaster. They changed my account, without my knowledge, from a 6 month interest free to an interest bearing account. I have cancelled club months ago, but am stilled billed for it. I have returned an item and repurchased another size, all on one slip, but they only entered the purchase and not the return. For every sms or e-mail I get charged. My account is paid up, but with all the wrongful charges, interest, non cancellation of club and not crediting my return, according to them, I owe them not R417.62. I refuse to pay for their incompetence. Since he took over, everything is outsourced, so one has to phone 3 different numbers and everyone is blaming the other. I am now being threatened of being in breach of contract and "handing me over". Why should I pay and be held accountable for incompetence?!?!
