Bad service from sales rep

They have beautiful cars, their service is bad. We haven't received spare keys, it's now a month already. And there's no communication I have to always follow up, make calls, drive to there with no solution. One time we were told that we can collect the keys, on arrival we were told that no one knows where they are. Fats who was our sales rep, deserted us the minute we collected the vehicle. Absolutely no after sale service. Secondly the car registration is not done, the permit has expired everytime we are told that the person working with the registrations is not at the office. This dealership is a complete headache when it come to servicing clients
