Big Bazaar / Futurebazaar / Future Retail / Hometown — BIG bazaar Profit CLUB Card

They make fool by making profit club members, First they offer 12k rupees worth of shopping at RS 10k but hey want 10k up-front . seeing the offer lucrative I also get one .
They seems to offering benefit first and I enjoyed shopping with it in first 2 3 months but real trauma came when COVId situation arises. I could not be able to visit their store due to locdown but when I got to visit their store in FEB 2021 then I came to know that my card validity is expired few month back. In scenario where even loan installment are being postponed by government they did not give extension of even 1 month to use my own money which I have already paid them upfornt.
NOW there customer is also very pathetic, after multiple request to extend my validity they did not resposne for 1month then one fine day they reply (after calling their customers care number) that my card validity was extended but again expired. Wow there was no mail/message/call for this information and they are telling I can never use that money.
BIG Scam.
