Disgusted service and totall *******

I took my BMW X5 to do diagnostic.Hugo came back and mentioned all the faults. My husband agreed on the service.Collecting my car the first day I had some issues.i had to take the car back everyday as there were still issues on the car.lube service,oil change,oil filter,Lhs outer cv joint,lower control arms,tie rods ends,wheel alignment,new sump plug,stabilizer links,skim rear discs,rear brake pads,rear brake sensor,gearbox oil flush,turbo recondition and service inter cooler was done all amounting to R43000.i took the car afterwards.when I am driving the steering rattles,the handbrake light stays on and Hugo still has the nerve to say I am not putting the handbrake down when I am driving.i noticed oil leaks in the parkade.i took the car back and now they says my samp were welded previously and now it's cracked that's where the leaks come from now he wants to give me another quote to have it fixed.i am ****ed as my car were in good condition before I took it there. I need my car properly fixed as I paid already a lot of money on a poor job done.he is now rude to me as I started complaining that everyday there's new problems and they just want us to foot the bill.
