Telkom Contract Cancellations/Service

Last year November an iPhone 16 turquoise was taken out on contract by a Telkom store in Lenasia trade route mall. A Friday afternoon my approval was successful however, upon starting up the phone the iPhone was found to be unresponsive and getting extremely hot. I had not opened the iPhone on Home Screen due to this issue.Ive then returned the iPhone very next morning and store advised that they cancel it and wave penalties so that when the issue is resolved they’d contact me to get a new one. Please note this was a Friday afternoon and Saturday morning it was taken back to the same store. I’ve waited a few weeks and eventually with all the fuss the store showed me this issue resolved. A week later an amount close to R960 was taken from my account.Please note that this is after the contract and credit memo was approved. I went back to the store AGAIN x50 and told the consultant, and he stated that I should stop that debit order. I did not end up querying that amount as apparently I was supposed to be credited. My main issue is that I’m now owing the value of that iPhone and is affecting my new iPhone from the glen Apple Store. I still however chose the Telkom network due to their quality service and speedy processes. I’m fed up to a point of not wanting to be on my device at all. I have a very busy call log and need my phone almost 24/7. This issue is now affecting the current iPhone taken out at the Apple Store. My line is suspended and would like to know when will I stop getting pushed pillar to post? Apparently Telkom does not cancel contracts and just eats your money? Store does not want to help? Agent on the phone cannot assist apparently? When will my credit memo ever be approved??? I’m currently using Vodacom’s network for a TELKOM device, so much for great service.
