boss. who did you pay? .. did you get a official receipt form the showroom where you are buying the car ..

I had similar issues .. I was dealing with a dealer who is now a police case..

I got my money back but after 4 months of hassle .. Bottom line "you need to have official payment slip for the money you paid to any showroom or service !"

Make sure that you reach the showroom and get official memo for the car and see written proff why things are getting delayed!

Good luck !
