Pathetic excuse for a retailer

I have purchased a microwave from Game in Durban, City View Mall. It was exactly 4 months old and I noticed rust developing on the interior. Since then, I have called the store numerous times. I have dropped it off more than 2 weeks ago and have been calling daily trying to get some feedback. I have been subjected to holding, calls being transferred from department to department. I have even called defy directly and still no avail. I am appalled, a microwave is a necessity, not a luxury. I paid my hard earned cash for it. The service I am receiving from both game and defy is putrid. I will certainly never be shopping there again.
