Still no help for cancellation !!! 2 months later

I received a response from Tim MTN Complaints Management Team: REQ:*** on the 30th of May informing me that the number has been moved over to prepaid and I will be credited for the additional invoices. I called the call centre to follow up and apparently this has not been done and referred me to a different department where I had to stay on hold for 30+ minutes. This is becoming utterly ridiculous. I just want the ****ing number cancelled I do not want it on prepaid. I want my debit orders to be cancelled as I was billed an additional r800+ rand after the cancellation notice. I will not bear any further charges to this and will be taking his to consumer friend and the credit ombudsman because this is ********! I want to be contacted regarding this on my cell number as soon as possible not just a lousy no action reply on hello Peter. I will have no further dealings with mtn as I have been a loyal customer till date. I will further not recommend mtn to any person I know to help them avoid services like this.
