I WANT MY MICROWAVE BACK!!

I sent a microwave to Bargain supplier shop at The Palm square in Parkrand Boksburg for them to fix it. My microwave was a Whirlpool brand. It could switch on but wouldn't spin and therefore I asked them to assist me. They never called to inform me on their progress with the microwave and so I kept going there to check on it and I would be told that they are waiting for whirlpool parts and that it is a struggle to get them. I never received even 1 phone call from the store. everytime I go there I would ask to see it and yes it looked like it had been opened. I then I went there one time only to find that my microwave is not there anymore, they couldn't find it. I was very upset and was told by one of the workers that one of the managers was *****ing from the shop and that he left with a whole lot of things, I guess it includes my microwave, apparently he took out one of the numbers on the contact number by the door so that customers are unable to contact the store. I took a picture of that detail. I was also told by one of the workers who is still working there that it will be point less to contact the owner for he pays no attention to complaints and that he is never at the store. I went there again to enquire on what they are going to do about this matter and was approached by a new white manager who basically told me that there is nothing they could do and that I should go. I want to be reimbursed for my microwave. I am tired of dealing with BARGAINS ! People are angry and tired of their way of dealing with clients. I live right next to that square and popes in every chance I got, but because the were using parts from my microwave to fix others, they never wanted me to take it back. I took a microwave that couldn't spin to them and ended up with nothing. I bought that microwave for R3900. Thank u
