Domino's Pizza — Coupon code didn't work for online order

Address:

Allahabad, Uttar Pradesh

I have a coupon of Buy one get one free offer. Coupon code- 414NXW6X validity date is 24th April 2015. First I called the restaurant and asked if I'll get another pizza free. They told me if I'll show them the coupon in phone then only I'll get it. I went to the restaurant and they told me to order online I ordered for medium category and every time it showed "terms and conditions are not fulfilled". There is no method to check the T&C. So don't send coupon if they are not gonna work ( or it's a glitch in the website ? ). I have wasted my time going to the restaurant. Else send the T&C too in the message. I request you to kindly look into the matter asap. It was a very bad experience for me. Aman Khare [protected]
