Group car llc

I purchased a benz from dis dealer 12 mths ago..ever since I left the lot I did nothing but repairs!! My financing co. gave me a deferrment after several repaies.Group car had a bogus repossession person repo my car...they have not contacted me as a real agency does to give an amount to retrieve my vehicle. These people at Group car are SCAM ARTIST!!! Trust me they never assisted me in any repairs!
