Poor service and poor mattress quality

We bought a brand bed (Orthopedic bed) for my daughter worth R5000.00 on the 10 Feb 2023 and delivered on the 15 February 2023.

My daughter complained on the second day that she wakes up tired. I thought maybe it's because she's used to an old bed and there should give it some time. Unfortunately it didn't get better instead she goes to school exhausted. She complained about the mattress been too hard like a rock. Onbthe 2 March she called crying and said her bag is painful and the way the bed is soooo hard you can't even seat on it, it is not comfortable at all.

I then called the outlet where we bought the bed same day 2 Marc 2023 and spoke to a consultant (Chris) and explained the concerns and he dismissed me by saying "Unfortunately we don't give guarantees on comfort" I asked hume again and he said "mam Unfortunately there's nothing that I can do". My interpretation is that once you bought a bed from them and you are not comfortable with they will not exchange and satisfy their customers. He then said when they give us a chance to feel the bed, my argument is, feeling the bed for 5 minutes is not the same as sleeping on it for 6 to 8 hours. In essence they makes us feel comfortable at the shop then deliver a different product. I'm very disappointed with their service
