Extremely Frustrated!!!!!

I have been a loyal customer to telkim for the past two years,account NEVER in arrears! At the end in my 24 month contract I went into a store on the 13th of November 2017 to complete my cancellation of the contract as I no longer required the contract.i was told that it takes 31 working days to be activated for the contract to be cancelled. I have been calling the call centres and going in and out of various telkom branches only to be told the same thing! "We have received you're application and it will be cancelled in 24hours" or "I have escalated the matter to my team leader" to a point where call centre agents even promise and plead that it has been lodged and I will have thus contract cancelled Two months later and I am still being billed as well as no contract cancelled!!! I never want anything to do with this company I just want this contract cancelled as I held up my end of the contract yet telkom is now playing me for a fool!!!
