Poor service

I will never advise anyone to take their vehicle to Kohler motors the service is **** I booked in a ml270 cdi 2001 gor a a estimated quote then got billed for a service done to ml*** model I paid drove my van a few meters away boom Epc error van switched off diesel spilled every where I phoned them they took 15 minutes to send out the technitian I ended up having to drive the truck to tow my van back to the workshop the same day after their so called service my van is worse than it was I go back I asked questions they do diagnostics I was told abs brake module failed I say ok quote me Im still waiting on a quote that was a month ago they over charged me and managed to mess up my vehicle further. Ps I knew my abs module is faulty before I took the van to them because I told them its faulty. They never owned up to their mistake and I'm still trying to figure out how my van went from a ml270 cdi 2001 to a ml***
