Aircel Postpaid Connection — Harashment on Consumer

I had regestired complaint no[protected] with Aircel for all the issues below but they never came back with solution except calling for amount settlement.
Not provided Reebok T-Shirt as promised while giving connection (Mohit from Aircel - [protected]),
Not collected 1st bill payment of Rs.140+ after confirming same by Aircel team.
No connection in North Karnataka Mudhol & Jamakhandi because of which could not use mobile for 1 month during Aug 15th - Sep 15th,
Adding late payment every month as since there is delay from Aircel side of not collecting bill,
Requested for soft copy of Itemized bill but never got it
Received many call for bill payment but my complaint was never resolved.
