Domino's Pizza — discount coupon invalid in second attempt

Address:	500015
Website:	goo.gl/CQThqp

Used discount coupon code crmb287c3b5d9 and paid rs. 363 through credit card. Money was deducted from card but transaction error occurred while redirecting from payment site to domino's site. So order could not be placed. Upon second attempt the discount code was declared invalid however it was not used as the order was not completed.
The coupon code should be made automatically activated upon failure in placement of any order or a new code must be sent to registered mobile number in such special cases.
