There is a code in the pack which you have to send to a specific number. You will then receive a paytm cash code for 15 paytm cash. Just once per number, and the paytm cash code is also linked to the number itself.
The noodles tasted fine, and the quality was as expected from Knorr. For those missing maggi can give it a try. First 10000 people who sms the code will also get a Chota Bheem Trolley Bag. Great for those with kids at home.
PS – I hope this is not the wrong forum to post this.
PPS – Separate T & C for Tamil Nadu buyers, which I am not aware of. Buy at your own risk.
