Cancellation stiil not done

I went to your Telkom branch at Middelburg Mall to cancel my contract that was ending in August which i was told i need to cancel the contract on the 1st of August if i dont wane continue anyone. I have done so on the 2nd August. I have waited until end of August and to find out that Telkom has not cancelled my contract. I have signed a cancellation form and it was send through to cancellation department, which i was told so from the lady at the branch. I went back to telkom and they looked on the system and told me that they have tried to contact me. Yes they have tried to contact me once and never again. I work daily from 07:00 till 18:00. The lady at telkom said she will make a note to them to call me again and i am still waiting for a call. I dont understand the fact that telkom at Middelburg told me that unfortunately they can not cancel your contract if they did not speak to you via the phone. So when i signed the cancellation document, that means like nothing and ot can not be cancelled ?? I have called the call centre i dont know how many times. Last time i spoke to a lady called Nqobile Mlambo on the 11th October and she said i must email her my cancellation document. She told me that she will escalate it to the rite department. She told me that she will give me a call back. So now this has been 3 month that i am paying for something i have cancelled. Is this the kind of service you provide as this is not acceptable at all. I have not used the sim since i thought it would be cancelled. Now my Wifi and the sim i cancelled is suspended but my own number is still working and never reopened after i made a late payment last month. When you try to talk to the call centre they dont even listen to what i am saying and they just shouting at you. I want this sorted out ASAP. If this has to continue i will most definitely take it further and i will never recommend you to anybody as this is very very poor service given and i can see that i as your customer has been given poor service.
