Poor service - Meyers motors

I bought a 2015 model Chevrolet cruze in November 2015 all to find out its aircoin was faulty. I reported it to the dealer, they asked me to bring it for repairs. To my surprised @ their workshop they said there was nothing wrong with the aircoin. I reported it till this year where they final agreed that they don't know its problem. They even asked me to leave it so that they can try their level best to fix it. My frustration is that they accompanied me to the taxi rank instead of giving me a courtesy car. I was not aware that they have that option up until I reported them to their customer care(Opel, Isuzu), unfortunately even customer care does not have more power more than them because they just told me what they have been told. And they are aware of that because they don't hesitate to release the customer care contact details. They just apologes for any inconvenience but not fixing or paying any loss. After they discovered that they cannot fix the problem they pretended as if they fixed it but on my arrival that's when they confess that they could not be able to fix it. Mind you I travel for more than 160km to fetch it and I left it with them for more than a week. Those guys know their story, the manager told me that they did not have a car they can give me at that time but they promised to arrange something the ff week but on the last day of that week they called me to apologes that they were unable to fulfill their promise. What frustrates me is that if they can manage to convince even the customer care with their manipulative stories surely they will delay until their workshop closed for this season. The manager had mentioned that the car is okay the problem is only the aircoin, that means the problem is not serious. I asked myself why did I decide to buy my car from Meyers motors because even the dealer promised to push them but to my surprise when I called him he said something totally differ (they ordered a new aircoin) from what they told me. While the workshop mentioned something about not having a courtesy car because they made it clear that they tried their level best to fix it but they failed.

Their service is very very poor!!!
