Terrible service !!!!!!

Samuels service centre durban briadene is the worst ever they are making money off peoples hard earned money.my car went in with tapping sounds only !!!!they inspected it and sorted it out!!! Upon going for my car it has no power to even go up a hill !!!! And the heat gage was rising !!! I re sent it back in and now hve my car with heat gage problems and has no power at all !! Asked the manager Craig the way forward he does not know !!!!! So you tell me what service centre gives you back a car with more problems than wat it had and still cant even apologize and sort it out !!!
