telkom service is pathetic paying for stuff that don't work

it's been months and I have been complaining for services not rendered we had our cables ****** in eldorado park and telkom told us after a month that they will not install cables we have to go get a voice line and i got Lte Huwaei line and we took out 2 tablets almost 3 years ago it was faulty when we recived it I phoned the company that couried it and i was told to take it to a telkom store they refused to take it back and I never activated or used the sim cards as it did not work it was only a year contract after that we took out the voice and Lte line out last year October it was already faulty becuase a tech brought us the phone and I collected Lte device from Northgate mall I had to return it as the sim cards was not activated and now it's been 2 monts the consultant at mall of the south informed us that we are still paying for Huwaei tablets and that we have to pay R1700 for out LTE line to go back on they never reversed all the amounts charged for the to our account and I have issues verytime I phoned for the last 2 months I have been getting the run around first they told me it was a tech problem gave me a ref number then i wanted for 2 months then everytime I phone I spend 2 hours daily phoning and no-one can help. I need the LTE and my kids have projects and I got calls from telkom billing and they told me that they will reverse services not used and I am still waiting and nothing i am really lost with words
