stay away from merc benz east rand

My ML250 went in for a service in 2017. Then a couple of months in the turbo went but my husband noticed many other faults. The car went in sometime in July. We got the car back and as always they give you a printout of what was done, now this is where the story takes a turn. Do NOT BE FOOLED, nothing of which they say they have done gets done. Why do I say so. A couple of months later the car went back in. Engine mountings were missing, gearbox faulty, front axle suspicious. Anyway apparently this all was corrected. Now it is the 29 March 2018. Received the car the 28th. It was booked in on the 16th March 2018, because NO ENGINE MOUNTINGS WERE DONE THE PREVIOUS TIME AS PER INVOICE, TURBO WAS CHECKED, ETC.... The car had though a couple of more faults. They reset everything that the car no longer locks when you drive off. The latest invoice says this was corrected, sadly not, the front axle or wheel still rattles like an isuzu bakkie and when you fone they tell u someone will fone back. At least the engine mountings were done. As per second invoice now. My advice, take your merc anywhere else but to mercedes benz east rand. This place is a joke. Your car goes in and in and in and in because their mechanics keep doing there own thing. They undo settings then they cant fix it. A rattle cannot be fixed, at all and I MUST assume they checked the turbo and gearbox since it is on the invoice like everything else, AGAIN.

What I do want from this complaint is a referral as to which Merc outlet to take my ML to for it to be checked correctly. It is no use going to the same outlet and expecting a different outcome, 4 times.
