Telkom

I had contract in March 2018 with Telkom for a 10G data(Wifi-rooter). however, since then I have never received any data but my account was debited every month. i have been calling Telkom every month since last year and they acknowledged their mistakes but never rectified. I got tired and requested that they cancell the contract because its not helping me but instead stressing me. I have been told its cancelled but Telkom continued debiting my account, until when i continued calling, I was told to cancell on-line. I did that in October 2018 and was given cancellation number but todate Telkom is debiting my money. When I call, they will tell me that i will be refunded and nothing happens, the next time I call I will be told the contract is cancelled and my money will still be debited. the next time i call i will be told i must pay Telkom R2000 for cancelling the contract. Then lately on Sunday the 14th whilst in church, they tried to call me and I didnt answer, they then send message that the matter is resolved. today on Wednesday the 24 April 2019, I asked how is the matter resolved, Im told the contract is not cancelled. Im just so tired with Telkom.
