Bad Service

I Thobile Maphalala went to Bosch car service Rifle Range at 12 Swartgoud Street,Ridgeway Johannesburg 2091 in March 2021 for the service of my Motor Vehicle ( Nissan Murano 3.5 ) which went in for repairs to have it running again. I was given a Quote of R26932.52 to get my car working again which i paid in full once all was done, i was given a warranty that should anything be wrong i should let them know which in a week something did go wrong my husband realized a oil lickage which we than went back and showed them the problem, then my car was taken again in so they could fix that to my surprise they call me back saying the car can not move again and had broken down so i was only told when i 1st took the car after it was said that it's good to go that i should only replace all moutings of the vehicle which was also stated on my final Quote of the R26932.52. Now i am told i have to pay again to get the car running R9k +/- for New set of Coil which was never said to me again now again today on 15 July 2021 i was told i have to pay R27k +/- as add on with the Coils to get my car running again, which now amounts to a Sum of about R70000+/- which is a new car all together so i am not happy at all about the service and refuse to pay all the other expenses cause my car was fine only issue was oil now i'm being charged for i don't know, why was all of this not part of my 1st Quote and now all i get is disrespect from the management and staff of the workshop. Honestly i never would have taken my car there if this is the type of ********** service they give us as clients and i suspect i'm being made a fool cause i'm a woman tell me where will i get all this money i struggled having to make payment of the 1st Quote but i managed to pay so i need Head Office to resolve this and want my car its more than 3months now with out my car.
