Airtel Broadband — Airtel fixed line "top-up" activation

Address:

Bangalore, Karnataka, 560076

I have been using Airtel broadband services since several years.
In December 2015 I got many calls from Airtel customer care or promotional team to avail "Top-up" unlimited STD/local outgoing calls.
Then I had requested (Order ID:[protected] for the activation of "Top-Up" on 10th-Jan-2016.
Till now I don't see any progress in spite of many follow-ups with customer care, Nodal officer and Appellate authority.
Even I have escalated this issue to Nodal team & Appellate authority. They use to reply with standard message
" Basis your email, please be informed that we have already highlighted your issue to the concerned team and they are working towards resolving your issue. They will get back to you with an update on the same at the earliest. Please bear with us!".

I really fed up with the responses and don't know whom should I approach to resolve the issue.

Once upon a time Airtel services was really good. Now the quality of their service is very poor and it's becoming worse year on year and not keeping up to mark. It's not only my opinion, even my colleague also facing lot of issues with Airtel services.

I shall provide the email conversation b/w me and Nodal officer/Appellate authority, if required.

Is Airtel resolve my issue?
