Reliance Digital — product not delivered after payment

Address:

PHOENIX MARKET CITY MALL BANGALORE

I bought refrigerator worth 54k and not delivered after many days. Store guys not picking call and when in called support, they said there is no purchase order on my name. Do I need to visit store again after paying money and request them for delivery ? After payment done, I need to beg ?
THIS IS RELIANCE AND THEIR TEAM FOR YOU!

Update : It seems they are not even reading review and just posting copy paste reply. I clearly called customer care and they said, no purchase done . They can't do anything as they don't find any history.
I wish I could undo to buy product from reliance. This was my last purchase from Reliance.

Update 2 : After several try they finally picked up call and have no idea about refrigerator. 3 guys came on call one by one and asked mobile number and said, I didn't buy any refrigerator. And then hung up call saying we will update you.
