[Resolved]  Big Bazaar / Futurebazaar / Future Retail / Hometown — didn't redeem my free voucher codes

Address:

232101

I went to the billing counter to redeem my free vouchers then the biller told me that the voucher wouldn't be redeemed because my purchase amount is less than 500, which is not mentioned in the message.
One of my friend had the same voucher and he redeemed yesterday on the purchase of 150 rupees purchase.
Today is the last date of voucher.
One more thing i want to add is that the biller and staff members who give free product on the purchase of other product, of big bazaar mughalsarai are worst in behaviour and nature, they just ignore us.
Do solve my problem soon.
