Mekor Mazda pockets my money and won't fix car!

I am still waiting for my window controls and material to be replaced SINCE MAY!!!<br> I have brought my mazda in 3 TIMES only for it to be sitting the whole day at the branch with nothing done! it was not even cleaned.I rely heavily on my car & it was a huge inconvenience for me to keep bringing it in.Prior to the 1st time my car was sent in,Mazda was made aware to replace my controls. NOT ONLY WAS MY CAR RETURNED DAMAGED with some material pulled out but I was also told 'yes the controls need to be replaced,I must book it in again.' This continued through to the 2nd & 3rd times I brought my car in,even though Mazda had on record the replacement that needed to be done & I confirmed with them to ensure they knew why my car was being sent in. I have paid a R500 deposit for the parts which I was told would arrive within the week.This was in JULY!Throughout the months I have persistently contacted the Claremont Mekor general and workshop Manager. 3 weeks ago I contacted Mazda S.A. NOTHING HAS BEEN DONE.I have all emails confirming my communications and their dates. This is excluding my telephonic communication.<br> Mekor & Mazda S.A. you have ignored me as a customer. You are a damn DISGRACE!
