OK FURNITURE KRIEL has the worst customer service

Well where should I start I bought a ps5 for zar13999 on the 17th of August of this year. On the 1st of November the ps started giving me problems where it would keep on crashing, so because it's under warranty I phoned OK and said it's got a problem and that they need to take it back, I was told quickly that they'd never ever received a complaint on a ps so there the problem started. They said I need to bring it in the upcoming Monday so they could send it back so they can see what the issue is. It TOOK THEM THE WHOLE WEEK JUST TO SEND IT AWAY, not only that but I had to phone them the whole time to hear what's going on because they just don't feel like I'm important enough to phone, so eventually they came and collected it. On that Friday they were emailed and said that the ps is out of warranty because no proof of payment date was sent with the console(after I asked velencia if I need to give to slips with it) and she only saw the email Monday? So 2 working days were lost because she didn't see the email??? So what do I need to do to get treated like I matter??? I'm out of the loop I don't get calls, I don't get feed back, so I did what any normal person would do I phoned to hear what's going on. When I phoned Velencia that works at OK furniture Kriel she started raising her voice as if I'm her child??? Is that fair I told her am I not a customer because I bought it cash so they can treat me like I'm not a customer???? Velencia that works at OK FURNITURE KRIEL, said she tried phoning the suppliers but they don't answer??? But when I call they pick up and they give me updates??? It's almost 2 weeks that I'm waiting on an answer for a faulty ps??? VELENCIA THAT WORKS AT OK FURNITURE KRIEL ONLY STARTED TO GIVE MEE FEED BACK YESTERDAY!!!!! And as I'm writing I KNOW FOR A FACT THAT VELENCIA THAT WORKS AT OK FURNITURE KRIEL WON'T PHONE ME BACK I'LL HAVE TO PHONE HER BACK TO HEAR IF THERE'S PROGRESS so it takes them 2 and a half weeks just to see that my Ps is faulty??? I need to speak with higher authority if it's possible, and I will never ever support OK FURNITURE KRIEL BECAUSE OF VELENCIA THAT WORKS THERE, SHE IS RUDE AND VERY VERY UNPROFESSIONAL, I PRESUME SHE TREATS EVERYONE THE SAME WAY??? SHE HAD ME AT BOILING POINT BECAUSE SHE IS SO UNPROFESSIONAL. I also tried with the other employees but they laughed when I logged the complaint
