Address:

Patna, Bihar, 800020

I had ordered Pizza for myself family on 14th Nov 2018 using the Andriod App on my Mobile. The application worked fine till the order selection and payment. The payment was done using Amazon Pay Balance and was collected by "DominosPizza " on behalf of Dominos. Post successful payment which was deducted from my account there was no update in the app and when I called Dominos via Phone they did not have the Order either from my Mobile. I request for full refund which has not been processed till Date. My transaction details are as follows.
