Cash Crusaders don't want to return money for the wrong product

My name is Moloi Tshepiso Johnny.On the 26/06/2021 I visited cash Crusaders in Phuthaditjhaba QwaQwa looking for a laptop.I was helped by cashier who showed me what I thought was a genuine laptop,only to find out that when trying to upload some files it was running shot of space.The IT man who was helping me he discovered that the laptop sold to me was a laptop tabblet with a maximum space of 28/30 GB.It was then I realised that I was given a wrong product as opposed to genuine laptop was looking for.Today 05/07/21 I went back to the shop to make them aware that the product was not what I was looking for.I was shown the manager of the shop and to my surprise he never listen to me and claim that I signed for the product.I tried in vain to tell him that it was better that he return my R2999.00,he was howling all the way to me without listening to my story.He finally told me that I must rather sell it to them not with the price I purchased it. I didn't understand what he was saying as I was expecting them to take their product and refund my money.The manager told me that he didn't take my money.I left that laptop (tabblet) there over their counter and vacate their store as I was now laughed at and no one was willing to help. It is my humble plea that hellopeter to intervene on my behalf on this matter.Mind you I was not even made aware that the purchased product is only only a CONVERTIBLE TOUCHSCREEN NOTEBOOK...Totally out and far from what I was looking for.No product knowledge of any sort explained to me.Its only when was made aware by the IT personnel that is written on the slip of that product.If I was made aware that it was something different from what I was looking for,I was not going to buy it at all as I MADE SURE TO LEAVE THEIR PRODUCT ON THEIR DESK TO SHOW THAT IT IS NOT SOMETHING I WAS LOOKING FOR
