Pathetic service with Telkom Mobile

<br> I sent through a cancellation form to Telkom to terminate my contract, my contract had already gone over the contract period of 24 months. I then sent through a cancellation form on the 1st of October 2015 informing them that I no longer want to use their service. I was told that I will have to wait for 21 days. Its been over 30 days by now and they have not attended my call and yet they still bill me every month. When I call them they tell me they are will in 3 days, 3 days passed nothing happened. When I call them again they tell me I must wait another 21 days. Thats pathetic. I will never use telkom mobile again. I advise everybody not to enter into contract with telkom mobile.
