Bad service.

On the 1st of September 2019 I purchased a lenovo ideapad core i5 laptop "which crushed the same day I bought" I couldn't return it the same day back to the shop because it was already late, the shops already have closed by. Did call the vodacom customer care which they responded that they won't be able to help me, I must just take the laptop back to the shop. I did took it back within 7 working days, the shop "REFUSED" to take the laptop they said I MUST GO BACK WITH THE LAPTOP BECAUSE ITS NO LOUNGER UNDER THE ! I must call the insurance to come at my house to collect the laptop. I did call the insurance, and they said they cannot come to my house I should personally take it back to the shop they will collect it there! And I will receive a confirmation letter which I haven't received it even today. Don't know what's going on but I need answers. The vodacom shop I'm speaking about it's 4U West Gate You can reach out to me ***
