Paytm — Complaint regarding free rs.26 paytm cash on Bourbon biscuits

Address:	400709
Website:	Paytm/britaniabourbon

I have been constantly trying to redeem the amount by entering the code available inside the wrapper from last 2 week. It alwaysdisplayed please try again after some time and from last 3 days it says that the offer has expired. I have many such biscuit packets at home which are left to be redeemed. Kindly look in the matter and let me know why am I not able to redeem the amount. Thank you
