Dismal service by the workshop personnel!

My almost 3 yr old Pseries was towed to them in July after it was bubbling and spilling antifreeze. Not that the vehicle wasn’t working, but I couldn’t drive it with that problem. They searched and searched and couldn’t find what the problem was and then asked to do an engine strip for investigation, they said it’ll take 3 weeks. All the emails I sent thereafter were ignored and today it’s 25 September and last week they asked for my logbook which I had to obtain from Wesbank, they said they need it for police clearance after the engine and oil cooler change. When I ask what they were doing for two months since they haven’t even claimed from warranty, all they can say is gibberish! I asked how long it’ll take them this time and the workshop manager had the audacity to say he can’t commit to any timeline. My friend had the same problem with these guys and his brand new car which had a problem stayed with these people for over three months and when he got it back a few weeks ago it coughed and stopped working, they took it back again. Do they know what they’re doing? I doubt! Worse thing they say THEY DO NOT HAVE LOAN VEHICLES! so I’m stuck here without a vehicle which I’m paying for but don’t have going towards 3 months now and they don’t care! Methinks they’re so used to getting away with this poor service and nonchalant attitude towards clients, and have never landed in hot water for it. I’m a film producer and a good friend of mine in a popular investigative TV show needs more people who have had a similar experience of substandard and dismal service from these guys. If you know of anyone, please respond here, I will keep watch for responses. I have gotten a handful of people to go ahead, but more wouldn’t hurt. I am sick and tired of commuting because of these people! I also pray that for their sake, when my vehicle returns, it isn’t *****ed up like my friend’s, because wow…do I have a surprise for them. Holla if there’s anyone.
