Telkom has extremely bad service towards customers

I logged a case with Telkom on the 6th February 2018 due to my WIFI account being incorrect, they were charging me for a migration that I never requested. I asked for it to be rectified and for my data to go back to the data bundle I migrated to in October 2017 and paid for in November 2017. I keep calling and keep getting told this case will be escalated however every second day when I call to get answers nothing has been done and still nobody assists with getting anything done, I just keep getting told its being escalated, how many times can you escalate something and still nothing done!!!!!!!!! Its been 2 months now and nobody resolves anything and its getting extremely frustrating and when I try ask if there is no other route I can take to get this resolved I get ignored.... I need this sorted urgently. I have never dealt with such bad customer service, especially for something that was done in error by Telkom themselves and not anything I requested... Nobody can even tell me who requested for this migration in January and how did that go through without any authorization from me. When I ask again I get ignored. Have emailed supervisors who have given me their email addresses only for them to not reply and not get back to me with any sort of feedback. I need sorted urgently or someone needs to advise me how I can cancel this contract so I can rather deal with a service provider which is willing to assist when I have a query on my account.
