Domino's Pizza — my little app voucher is not accepted - no reply on jubilant mail id even after 100 emails

I am so frustrated by your support that i really felt that i am being cheated. I have sent 100 email to your guest care dominos email id but not even single response. They are not bothered to listen to customer. Adding to this. I was being told lie two time first time one of dominos executive committed that i will get my money 500rs to my paytm account as little app voucher is not accepted now by 8 dec 2017. Then on 21 dec i was being told that now i can use it both times a big lie to customer. Now i am getting reply third time we can't help. Little app will provide the refund. Little app phone number sucks in email they are responding three time like talk to dominos. Now my money is stuck between you two. I have also looped them in email id. But you are not bothered to at least reply or take extra step to resolve customer care. You should inform or liaise with little app and get it sorted.
