Dishonest , unreliable dealership

I bought a car from this dealer 2 months ago, now I am experiencing some mechanical issues with it, and all I need is for them to register the motorplan under my name so I can get the issue sorted out myself. They a They have been giving me the run around and unfulfilled promises to call me to resolve the matter. when I call Dre is always on the road and tells me he has escalated the matter to Michael who has been avoiding any contact with me. Their after service is very bad and I am starting to doubt their operations as they are not upfront and honest in their dealings of my case.
