Very poor service

I received bad customer service from Lukhona at hi Fi Fourways crossing. I bought a 55inch LG smart tv 2 years back and paid for extended warranty. On the 29 of august 2021 I called the store to report a fault with my tv and was told that they will log the call with the service department and I will be assisted with in 14 -21 working days, and if the tv is not sorted by then I can come claim another tv at the same value. To this date I have been sent from pillar to post.
