Telkom adds contracts to your account without permission, charges for something I don't have

Telkom needs an award for the worst service provider in SA ever!!! I have cancelled 2 of my smart plan 50 contracts effect date 28/02/2018. On my March statement I see 2 new Free Me 10GB contracts @ R411.19 each. I call the call center and ask how did this happen they cannot help, go to the Gateway branch and they look on the system and say they cannot help because it was done on the back office, email Telkom a couple of times and no response. Send TelkomSA on mybroadband a message and the Telkom manager at the Gateway branch calls me and says they it will be sorted out in a couple of days and they will give me feedback. Don't get a response so email him back, he doesn't reply! Log a dispute and still don't get a response. Debit order with an extra R822.38 charged to my account on 26th March, I go to the bank and reverse the debit order. Get charged R60 to get my own money bac**** Email TelkomSA on mybroadband again and I get a reply saying that the billing department will contact me, nothing happens as always. On my statement for April I see the 2 unkown contracts still appear and a charge of R200 has been added to my account for reversing a Telkom error. I've been with Telkom mobile for 5 year's, is this the kind of service I am going to keep getting? I don't even want my recently upgraded contract that I've taken from you guys, this service is just too pathetic
