Reliance Digital — Scam

Address:

Reliance Digital Shop, Patliputra, Patna, Bihar, 800001

I ordered a prepaid iPhone 11 128 GB Black from reliance digital app through insta delivery method which promised 3 hour delivery on 6th June 9:45 AM IST its been 3 days I have not yet received the order and called the customer care executive several times and they gave me the contact number of the shop which was responsible for delivering my order. I called on that number on 7th June they promised to deliver on 9th June then I called that guy whose name was Piyush Kumar, CRM Reliance Digital, Patliputra he instructed me to cancel the order as they will not be able to give me my order. I called the customer care and explained about this and asked them to cancel as I will never purchase anything from reliance company. And now I have been waiting for 6 hours to cancel my order as there is no option available on the reliance digital app to cancel the order I am totally dependent on them. Please help me they have my money and not delivering the phone what should I do, I have waited enough.
