Account not closed as requested

I recently had LTE Uncapped installed at my home, where I previously had a 10GB + 10GB Internet.<br> I requested that the 10GB account be closed as I would now be paying for uncapped LTE and did not want two accounts. I was told by the Telkom person via e-mail that this cancellation would take place after installation. I did not use my 10GB Internet after I received the LTE, and Telkom still took the R199 off my account for the 10GB plus 10GB, for the whole of December. I demand that Telkom reverse the money taken from my account, since Telkom promised that the account would be cancelled immediately, and I have not used the 10GB package since having received the Uncapped LTE package.
