I booked my vehicle through csd in the month of march and received the vehicle in the month of april and after deposited all the money of insurance and essential modification expenses and other expenses i could see the vehicle. What pre received inspection i will do after depositing all the money. Then after getting temporary registration of my home town of gorakhpur i did bharat series registration on 18 may 22 and forwarded the copy of registration to agency for no plate and they told me that it will take 10 days for no plate but when i called after 15 days ouality manager told me that it will take another one more week and then i called after 12days phone is not picking up nor i got any response about delay. Suggest me the course of action.
