Paytm Mobile Solutions — offers shown on mobile app is incorrect

Address:

Hyderabad, Andhra Pradesh, 500006

This is regarding paytm postpaid payments. The app shown an ad with 550 cashback with t&c but i couldn't find anywhere when i click on the ad. I tried reaching customer care and he has mentioned that there is some other location to find t&c and the offer is from 11th apr 2018 onwards that too for 50th customer. When i asked how will we know if we are 50th customer or not then he replied it will not be know as it's autogenerated. So my concern is how will people know if they are 50th customer or not and i seriously doubt if they have some algorithm in their system which provides such thing. I ask authorities to take a look into this and let us know if anything
