Airtel
DND calls

My airtel no is 7869047223.

I have send msg regarding DND activation on 16th April.

Even after 2 months and 7 days, I am receiving promo calls from airtel.

My reference no. for registering on NDNC is S 1017362457.

I called customer care regarding this matter but they are not helping me.

NOW YOU TELL ME FOLLOWING THINGS:

1. AS PER TRAI RULES PROMO CALLS SHOULD HAVE STOPPED WITHIN 45 DAYS.

SO HOW TO FILE A COMPLAINT AGAINST AIRTEL?

2. AS PER RTI ACT OF GOVT. OF INDIA--TELL ME WHY ARE PROMO CALLS STILL COMING ON MY PHONE.
