5 Months with no Feedback

I recently moved and I have filled in a 'contact us' form on the Telkom website at least three times in order to cancel my connection at my previous home. No one has bothered to reply or contact me in regards to this. Now suddenly I get invoices for R900, where my account was ? R190 each month.<br> <br> This is absolutely unacceptable. It takes forever to get through to a representative at the call center, and once you get through it seems that no one really knows how to help or even know what products you provide. Even if you go through the trouble to visit a Telkom store, the wrong information is provided.<br> <br> This is my 4th letter to Telkom explaining my predicament. Please tell me what else can I, as a consumer, do to get some good service and connectivity. You advertise this unbelievable \FUTUREHOOD"living"
