Unhappy about the service

Hi there, I bought my 32L Samsung microwave on the 4th of November 2017(along with a number of electronics). In the end of November 2018 my microwave stopped working and I called in Game Mall of Africa and spoke to a gentleman. I explained to him that the microwave is a year old and that it is flickering and doesn't heat food anymore. The gentleman said to me "Mam your microwave is still under warranty, kindly bring it in and go straight to customer care".

I took it in on the 8th of December 2018. I have been following up regularly because I have no food heater at the moment, and they have told me that the supplier quoted me R1065. This was not communicated to me when I called in before I brought it to the store. Also when I call Samsung South Africa ,they tell me all their microwave have a 2 YEAR STANDARD WARRANTY, therefore I do not understand why the quotation.

I am extremely unhappy with the service I am receiving from GAME MALL OF AFRICA as a client who purchases there regularly. I would like my food heater fixed as soon as possible. I have provided them with proof of payment. Kindly assist
