Dealing with cases

I am totally disappointed at how my case is being handled by MIOSA, the pain of buying a car then have it broken within five (5) months and instead of suing the dealer I trusted them to handle the matter instead the car is just sitting at home and whenever I call they say they are still busy with the case, doing what exactly??? Till today and I'm sure the car is even more damaged now. I should've just fixed my car instead of trusting the system to fight for what is right. It's been exactly 5 months now waiting for them to tell me what to do with the vehicle since they told me not to do anything with it and it's so painful.
