Worst service EVER!!!!!!

I cancelled my Telkom Mobile Internet 5 Promo contract in mid-July this year. However, I had to call countless times to follow up on whether the contract had actually been cancelled as Telkom Mobile continued to debit my account each month. After speaking to Collen Phiri in October, who was very helpful at first, I came to find out that the contract wasn't cancelled since July when I followed the cancellation procedure on the website! I tried the online chat facility this morning and spoke to Diana Petersen, who claims that there's nothing she can do as there is no information on the system. How can a trained Customer Service Agent respond in this way to a client? After months of incorrectly taking my money, Telkom hasn't bothered not once to give me some feedback on the refund that I had requested. <br> I will be drafting a letter and sending it to the Sunday Times, mentioning names of all the people I have dealt with. Honestly the worst company ever. I would rather pay 10 times more but get proper service.
