Disgusting Service

On the 06th of November 2022 we purchased a phone at Mr Price Birch Acres Mall and it was not in a good condition and took it back within the period of 7 days and Jemia ( Sales consultant) took the initiative to be a Technician which took him for ours to find the problem and could not even find, and said the phone was fine. We still encountered problems with the phone, and took it back and he said he will book it in for service, mind you this is a brand new phone( how disgusting and pathetic) phone was taken in and still we are encountering problems. On Saturday we took it in, Jemia called the Area Manager ( Christina) said NO it must go in for service again.

My question is that the Terms and Conditions says Phone maybe returned within 7 days and we will be given our money back but nothing whatsoever,

Can this be solved because this is absolutely nonsense
