This is to inform you that i bought 12 packets of Knorr soupy noodles and the company is showing advertisement (currently also) that customer will get Rs15 Paytm in one pack of knorr soupy noodles. The coupon was there inside the packet but it was not working. Basedf on that i informed customer care and they registered a compliant on 14 October, 2015with No 2970062. and ensured me that solution will be provided.
There supervisor Mr Rahul Dutta and Mr Swapnil ensured me that i will be getting the solution from them within a week (i also have email from them) but till now they are fooling me and delaying the response.

Appreciate if you can take action specially for those companies who are running fake advertisement on television and other media just to attract consumers by running fake offers and fooling customer
