Telkom Mobile is Useless!!

I upgraded on my 2 lines in September 2015 to 2 x packages for R399 each. Upon receiving my first bill, the bill was R2130.76, only to find out that they had added on 2 x data bundles onto my account = R721, which I never requested! I lodged a case in October for them to be removed. After a lot of fighting with customer service, they eventually got a someone to call me and she told me that the data bundles had been removed and my account was sorted out. I am still being charged every month for an add on internet bundle of either R93 and in January and February, it is R350?? They have still not removed these data bundles from my account which was never ever requested! Customer service admits it is a fault on their part and I have had to lodge another case AGAIN!! In the interim my account was suspended last month because I refuse to pay for something that I never requested and last week, my line has been fully suspended (I can't even receive calls). I am told I have to pay R3 185 when my account should only be R1600 for Jan and Feb and then wait for them to resolve the case! That is pathetic!! I will never use any of Telkom's services again and definitely regret renewing my contract
