**** to by Telkom about ADSL to LTE upgrade

In October last year I got a phone call from Telkom as they are converting from copper to LTE or Fibre. Unfortunately, as we do not have Fibre in our area yet, we had to change to LTE. When I spoke to the original agent who phoned me, and subsequently the other agents I spoke to for clarification and better details, I was told that nothing would change except that we would be on LTE instead of fibre. In most of, if not all of those phone calls, I asked if it would extend our 24 month router package contract for another 24 months with Telkom or if the current contract would still be the one to honour and end in Feb. They all assured me that my contract would still end in Feb and NOTHING, NOTHING at all would be different. I found out at the beginning of this month that they **** to me about the contract. They did lock me into a new 24 month contract, without my permission. They also **** to me about everything staying the same. The FUP was a 900GB cap on copper. With LTE it starts being throttled at 150GB. I have logged 3 queries to ask for the recordings of my conversation with them and to find out about all of this. Each time I am told that the back office will phone me back in 24 to 48 hours. 3 weeks later I am still waiting. I'm reaching the point of going the legal route as this is not only extremely poor customer service, but I have been locked into a new contract that I was never advised of until after the contract was locked into place and that I did not give permission to.
