Big Bazaar / Futurebazaar / Future Retail / Hometown — 11,000 vanishes from Future pay wallet overnight!

Hello my Future pay wallet amount was completely wiped off on March 1st, 2021.
I was asked to deposit about 10K when I first purchased the card..and I was told that I will get the unspent amount automatically refunded into my account at the end of the term.
But then I kept receiving calls asking me to extend the deposit - due to CoVID - etc...I was also told afresh that the money won't be refunded automatically..some long drawn procedures were involved it seems. To my disappointment today my Future Pay App shows zero balance.
I have the number of one representative with whom I was talking to : His name is Naveen
His number: [protected]. (From somewhere in Phoenix mall, Whitefield..Bangalore) .
Can I hope to get back my money from these scamsters ..who collect money from customers with ease but give them a hell of a time to pay back what is rightfully due to them.
Prabhu
