Over heating brand new laptop bought at Exact Protea Glen mall.Hp product

I had a bad experience with the store manager after purchasing a laptop on the 22 November 2024 HP product.the laptop is faulty and the manager is refusing to take it back.he gave me the contacts for Hp company to contact them so they can help with repairing.i am still with the laptop waiting for him to follow the process of repairing.meaning I am part of the process as a costomer.He was given the authority by area manager from hi shop to take it but he seems to be difficult
