Bad customer service

I bought a television at gamestores parow centre thr television was faulty and I return it at 27 August 2022 t was bought cash but the lady Nina at customers service wanted a bankstatement to show that the amount was drawn wich to me was unacceptable she insulted and questioned us infront of evry one and customers who was in store I requested for the manager Eugene who said he'll sort everything out.The television was sent for repairs but after 1mnth and no feedback from anyone although I reported the case to customer care service for complaints.After 2a d a half mnth they informed me the the television wasnt under warranty a d we hd to pay R3500 if we want it to be fixed.I decided to fetch it but the way the a d attitude of the the people in gamestores parow centre I suggested that they must be send for customer service training. Till now no apologies or communication from the manager. It was a worst experience and I dont prefer to go at gamestores parow centre.
