Bad Service....is OK!

I purchased a Denver TV unit the 20th February 2025 at OK Mitchell's Plain. I arranged too have it collected the Saturday morning. Paid the person R300 for it to be collected. When we arrived home we opened and found scratches and the one door hanging abit making marks on the bottom of the cupboard door. The top surface of the cupboard also had marks on unfortunately cannot be wiped off. I told the sales person that I would check immediately when we get home and informed him, which I done. I have been making several calls and WhatsApp messages with NO solution to my problem. I have only received an answers 2 weeks ago advising suppliers only came back to OK now asking for more pictures as they claiming it's not a Denver TV unit. Then I was told that "Higher management" will be handling this issue. No surprise... NO ONE of higer Management EVER called or emailed me. I am sitting with a boxed TV unit in my lounge, should I arrange again for someone to drop it and get a refund which will cost me again another R300 and I will be a looser of a R600 because of OK bad service! Why can't I get feedback of how this can be resolved? Why is it costing me to make calls for updates? Either I get a new unit asap or OK needs to come collect this unit at our house with an immediate refund! Let's see how long I wait now for a reply...again!
