Bad feedback, service and support

I purchased a laptop from the Fourways store on 25 July and in the second week of use there was a couple of issues where the systems froze, overheating issues and the speakers stopped working, continuous restarting. I took the laptop back on the 8th of August.

I phoned numerous times but have not gotten feedback on what is wrong with the laptop to date, 22nd August.

With such bad service I would like a refund.
