Printvenue — Coupon code not applied

Address:

560068

I have made an order, coupon code was not applied. Now if I call customer care, they are not responding well. They are not cancelling my item and not applying coupon code. I have called them immediately after placing order. Cancellation policy is complete humbug. They say we can cancel within 1 hour, but I called immediately and they said that it is already processed.
