A very angry customer

I bought a car (Renault Clio 4) at Nissan Benoni in May 2017, i took an extended service plan and warranty. In February 2019 I took my car for a service and they broke a nut and made me pay for that nut they broke and it was not my fault but i payed for it coz i wanted my car. On the 12th i went to Nissan at Benoni and told them that my car has a problem when i apply gear 4 and gear 5 it makes noise the the manager by the name of Vincent checked and found out that my car is still under warranty he then took my keys and test drived the car and he heard what i was talking about. He then called Rex diff and Gearbox after he said i should bring a car on Monday so that they will take it to Rex diff and Gearbox and i did that, i took my car to Nissan on the 15th July 2019 and left it there and he said it might take 21 days.

I called him yesterday the 1st of August 2019 to find out what is the progress and he said let him call Rex Diff and Gearbox he'll get back to me and he never called me. I called again today on the 2nd August 2019 from 8:30 am they transferred me to his office with no answer i kept on trying the whole day with no luck. i even left messages to the person who answered the phone and she said she did pass the messages to Vincent she even sent him an email. I called again Around half past 4 pm he still ignored my calls i then asked the lady to put me through the lady Disher the financial adviser . I explained the story to her, she said she's going to Vincent and i said i'll hold, she went and never came back and i waited for about 8 minutes ,they sent a guy to tell me that Vincent will call me . I said i'll hold the line then they hung up on me. I called again and I was now angry coz they made me look like a fool, when Vincent answered the phone He said He's been calling me and he couldint get hold of me and by that time i was on a phone waiting for him and left my phone on my desk . I told him that he's lying coz i've been calling him the whole day but he was ignoring me. He said i must not call him a ****, i then asked him about my car and he said he wont tell me anything until i apologize to him.

Im very disappointed that after we bought their cars that's how they treat us. #very angry customer
