not recognizing someone to use Car Service City

took my vehicle because I had a noise on my Cv the manager charged me R600 before I even took the vehicle in and when the car was there he changed that he has to do inspection 1st okay he called telling me noise coming from CV which i knew about coz there is a missing pin which wasn't there and he quoted me R3.300 to fix i asked him how the amount got there but he promised me R600 he said their labor is 1550 and parts another 1600 that was ridiculous coz I told him I have the part missing with me no need for you to buy as we discussed it before I bring the vehicle to your workshop they said if I can't manage I've to pay 745 for telling me that the CV was making noise

fine I went to pay and get my car back even not fixed as I made arrangements with Tiger Wheel Tyre for fixing with R450 I found my car engine stripped and not starting there was a similar car in their workshop asked them why my engine parts are stripped coz it's got nothing to do with CV joints they denied striping and the mechanic came and put everything back together I drove the car home when I get home I saw smoke coming on the bonnet called mechanic and he confirmed the temp sensor seal was missing

like serious seal cost R9 at the dealer that's what these guys from Car Service City stripped my vehicle to ***** and after that charge me to tell me the problem I told them what the car is doing without even fixing it
