Teljoy do not keep there promises

I have being doing the rent to own on a TV threw Teljoy, my tv blew after having loadshedding. I contacted Teljoy around the 10 August 2022, to which the TV was collected on the 15 August and then sent back to me as un-repairable a week later. I was told by the Technician that I must take the broken tv to the warehouse to swop for a new tv. Upon me speaking to Teljoy about this they confirmed that they deliver the new tv and collect the broken tv and that some one would contact me to arrange the delivery. I have been dealing with Marchell Brits and Leanne (Workshop Manager) and Teljoys online services PLUS numerous other consultants telephonically, i kept getting told there is no more Hisense TV's in stock, then I was asked what other TV brand, I gave the names and was told again no stock of any other TV. I have asked Marchell to provide me with a managers number and i get ignored with excuse after excuse. It has now been over 2 months that i am sitting with an un-repairable tv and no body is assisting me on delivering a new one. I have even commented on Facebook and of course my comment was removed and no contact. I am at my ends wits and cannot believe the service i have received from Teljoy. If they don't have stock of any TVs then how are they still advertising or even have a business to continue running.
