Refund and bad service.

Good day. I hope this email finds you well. I have an issue with the manager and consultant from the OK Furniture Midrand boulders branch. I purchased items worth R15k plus on the 30th of May 2024 and user bdm02 assisted me and him and this other colleague of his who is Venda (forgot his name) said they are testing the TV, i then get busy browsing and looking around because i wanted to buy a bedroom set, wardrobe, Tv stand and a bed also. they then asked me to come see that the TV is working, when i get to where they were testing it, it was then off because they switched it off before i can even see if it was on, i even said the words ( its fine even if i didn't see if it was on and they laughed and didn't even bother to at least switch it on again so that i can see it on. the following day which was the 31st of May, I then went back to advice them that the TV id not working and it has issues, i asked to speak with the manager and he then came to the floor, i explained the issue to him, and he said that I signed the TV Verification stamp. and when i looked at that stamp the consultant didn't even tick these boxes that explained if TV has scratches, working, dents or issues. the consultant then went at the office and tick then and then come back with it ticked. I then asked the manager to ask the consultant if the day of a purchase he did complete the TV verification or not, he then told the manager the truth that he did not do it yesterday, why i don't know. I then asked the manager to check the cameras and he would see if I was near the tv or see it, or see on a camera if the TV was working if the angle would allow him. and when i was talking they all walked away laughing at me and telling me that they wont give me my refund and i can go whenever i want. I then asked to speak with a regional or opps and they refused, i even asked them to at least let them know of the situation, i left my contact details and even today I haven't received any feedback. and that same day i had to buy another TV because at home they needed TV. so the one i have they tested it and its fine. Now I spent R14k on just one TV. I have worked for a Shoprite group for 4 years and I know that you have quality and best service, that's why early this year we spent R40k plus on furniture at OK. you are the best when it comes to customer service and goods. I was so disappointed with these nowadays consultants at OK because during my time we never treat customers like this, that brunch I will never buy anything from it anymore, I will continue busying from OK though because you have good and strong furniture. I know I can't fire the consultant because it's not my place, but knowing Ok furniture that's not a consultant you should keep unless you care about money not service, because he might not be fired because he makes more sales, but that should not be a reason to keep someone like that. who laugh at customers in front of his manager. and these 2 cashiers i could see that they were so disappointed with the way that guy was behaving and treating me. I mean I looked like a fool in front of everyone. I even asked him if I said (I didn't see it but I'm in a hurry and needed to go) and he even agrees in front of his manager. Please assist or advise, because I need my refund, and to show that I needed a Tv I even bought another one that day.
