Big Bazaar / Futurebazaar / Future Retail / Hometown — cheating by deducting money without my knowledge and consent.

Big bazaar located at the kalkaji metro station has employed persons mainly the billers and the administrators who are cheating the customers. One such cashier duped me of rs 359.97 reward cash from my bank account. I presented him with my debit card for the payment, but without my knowledge and consent, he deducted the hard earned rs 359.97 reward cash and then befooled me by stating that i would have to pay less. I raised the issue with the store incharge and the administrator, but they too befooled me by giving one reason or the other. I then contacted big bazaar customer care who assured me of necessary help, but to my shock nothing was done except a call from the store where i was befooled again.
