Impossible to cancel contract

I moved to KZN from Pretoria and do not get Telkom mobile data service where I now live. My data contract expired in December, and I have been trying unsuccessfully to cancel the service since the 22nd of December. Firstly, Telkom makes it very difficult to cancel - you have to email documentation and wait for a phone call that they will allegedly make to you in 22 working days. That didnt happen. I have made subsequent attempts to sort it out and each time the matter is 'escalated' with the promise of a phone call within 72 hours. It is now February and I have not had a single call from Telkom.<br> Shocking.
