Serious Problems to close LTE account

I tried since 25 October 2016 to close my LTE account with Telkom. I relocated from Centurion to Mossel Bay area and no LTE service was available then. I followed the correct steps to close the account/contract and followed up a number of times, but to no avail. Except the automatic reply that says they will resolve the issue in 21 days, nothing happened. I had to enter into a local Telkom ADSL contract, because of the unavailability of LTE at the time of my arrival. To get someone with the necessary authority to respond, seems to be impossible. I picked up the other day on the George community social site that there are a number of people with similar problems and when I scrutinised Telkom's site I even found persons there complaining about the same problem. The local Telkom shop stated that they are not authorised to deal with that problem, however they did send a request and I received a case number. No surprises when that avenue also delivered no results. I am frustrated about the inaccessibility of Telkom systems and an easy way to address customer care problems.
