Trai — not getting hd connection service as per offer

Address:

Mumbai City, Maharashtra, 400008

I have installed airtel dth in month of January and it was in offer with 3 months free HD pack and I was told that offer will remain as same even after new trai rules. After 1 month, all HD channels are stopped by airtel and despite of calling customer care services since last 3 days they are saying issue will be resolve in 24 hours but still no progress. I'm really frustrated calling so many times.
