Poor Service Delivery

Everything was excellent until the sale was finalized. Then it started going wrong. The biggest issue was that they registered my wife's car under my name, no apologies or anything. HOW DO YOU DO THAT and still have a job? Then we started waiting for the settlement , it has now been a week. Every time I enquire about it I get, IT HAS BEEN SUBMITTED FOR PAYMENT, WE MAY DO IT TOMORROW. I've dealt with many car dealership over the years, this dealership for more than 10 years, and this is the worst service I've ever received. I've escalated this to the Dealer Principle and is still waiting for some kind of resolution.
