Ford India — Financial issues - change in the committed price & no receipt for payment

Address:

I have booked Ford Ecosport in Dec 2016. It has been 3 months now and I have not received the vehicle yet. Every month the dealer asks for more money than the price given at the time of booking. After receiving the entire payment, they have not given any receipt.
The escalation was to the corporate office but still they dont resolve the issue.
This is a sheer case of misleading the customers
