Do you have the PBO?
The cheque will be given after the vehicle is delivered and the amount would be calculated for number of days between PBO date and Vehicle invoiced date.
So after delivery you'll have to keep calling and sending emails to pak suzuki and the showroom.
Manufacturers have to report the compensation given for late deliveries every 6 months and they can skip one cycle citing fake reasons (like it's routine in Pakistan)
Before the vehicle is delivered all you can ask for is order cancellation.
