Very poor service

I have bought my vehicle 10 days ago They forced me to pay immediately without any inspection on the car ,the mealage was 2000km more than what mentioned in offer to purchase after receivingthe car ,the Matt was torn off and the replacement was in different size ,taken from other model and not fitted. Every day it slips under my feet and reminds me how BMW can be poor and disabled to make the client happy even after send them feedback directly!
