NO CLIENT SERVICE ON CANCELLATION

I was due for an upgrade in July for two of my contracts, but because of the poor service the last year I decided to cancel the contracts. I contacted the call centre and advised me to get a cancellation form at a telkom store which I did. Completed the for at send it on the 22 August to ********** as the contracts will end 30 September. Called the call centre end of August and they confirmed that they did received the form. End of September I called again and they confirmed that they received form. It has been a week in the new month of October of calling the call centre every day as they did not cancel both contracts and is still billing me for the devices that is paid up and the subscription fees. Every time I call the call centre they say they will get back to me. I have even emailed a consultant every day Senzo Nhlapho ********** who has requested the form again and promised he will get back to me since Monday, but with no reply whatsoever. Telkom please cancel my two contracts and stop billing me.
