Samsung customer care is S##t

this is the worst service i have ever received from any business. on 9 June 2021 i took out a contract with Vodacom and did a add on item (samsung qled tv). on 22 July 2021 there started appearing a line on the tv after many struggles and finding out Vodacom does not fix it or exchange it, Samsung does, we logged a call on 3 August 2021, after calling Samsung every time and they just advise someone will call me back, no one calls. the only way I can get feedback from them is to do a live chat which they even state someone will call, eventually on 3 September I received a sms with a reference number, but if you log in it shows no call open for this reference number. Samsung called me on 17 September to ask why i reviewed a live chat badly, to which i explained the lady my problem is still not fixed, she just apologized then. on 21 September 2021 samsung called me to advise once again that the tv will be exchanged but it will take up to two weeks, I AM STILL WAITING!!!!!!!!!!!!!!
