Big Bazaar / Futurebazaar / Future Retail / Hometown — Money deducted from bank account & transaction failed

I had my order ready through Big Bazaar online app & proceeded to make the payment using Future Pay wallet. My money got deducted & the transaction failed. It’s been more than 3 days, I’d mailed Big Bazaar as well as future Pay but there has been no response. I also raised a complaint through the app & tried to call for support but no response whatsoever from anywhere. It looks like they don’t give a ### about their CUSTOMERs. I advise everyone never to try placing an online through Big Bazaar ever again!
