Domino's Pizza — late delivery. against your claim of 30 min guarantee

Address:

F/289 shaheen bagh abul fazal enclave 2 jamia nagar, 110025

I ordered my pizza and waited one hour. My pizza order is done throgh paytm on 26 march 2019 (today) and order no. was 225. My address was shaheen bagh and call no. -[protected].
I asked the delivery guy whats the problem
I showed all the terms and condition mentioned by ur dominos. He was so care free and told me u will get refund. He told me that u will recieve ur money online after 7 days. When i asked for how should i trust u so he told me to take his manager no. And talk to him. I told ok one should believe not everyone is cheater. So i dont have trust issues but u should do ur job correctly. So he told me ok mam i will go and cut this reciept that it was late something about the process.
Now i dont no whether he had done this thing or not atleast u should send a msg before actual transaction that ur payment will be refunded etc due to the late delivery including your apology.if thereBut is a proper way of complaining about this thing tell me? i think ur service need to improve.
