Bad service

I bought a car in june at Hyndai Airport from Senamile pathetic service i get from these people its so ridiculous.. I bought a car in june until now i haven't received the key even today been sent from pillar to post, on the other hand they sold me a car knowing very well the car has radio fault.. One of the consultants even confirmed to me that the xar had that fault before it qas sold to me.. Ive been calling texting no one is getting back to me.. I regret doing business with such unprofessional and inconsiderate people
