Airtel — I want to sue..getting threat, insult, and harassing by airtel so called recovery agents for unreasonable bills

Address:

Gandhinagar, Gujarat

I am using airtel no. since 4 years until last few months.
I faced lots of network problems and due to my hectic schedule and some uncertain personal problems, i never got time to keep on complaining,tracking and being in waiting queue.
Later I was recently surprised with a monthly bill amt of 4k and with total of 7500 of last 2-3 months which i intentionally didn't paid until and unless I could have got the reasonable waiver after cross checking.
However my no. was barred from outgoing and incoming service but i still kept my sim on though I had my other reliance no. working.

However to my very big surprise, on Sunday(Holiday) dated February 26,2012,my friends, relatives,paternal uncles calls me up and says they are getting calls from so called Airtel agents Pankaj Shashtri and a lady complaining, abusing and insulting me about my bills and asking me about my whereabouts.
I was totally depressed and furious to see such unethical irresponsible behaviour and such a disgusting unprofessional attitude of recovering.

Later on same day, the lady also called up my elder sister and asking her to pay the bill.
My sister was being insulted at personal level, later my brother-in-law when took over the call, she insulted him as well and ask their address so that they can get them in trouble if they or me doesn't pay the amount they ask.
My sister has nothing to do with my mobile no. and bills. Why they called her, my cousins and friends?
I totally lost my social respect with just
My loving parents were nomore since 2 years due to unfortunate heart attack.
These people weren't even scared to go analyse my personal life,my personal connections,insulting my social respect.
It was beyond patience when the lady even insulted my sister's emotions arrogantly saying as if 'we have lost our parents, this is why we don't have culture and roaming like frauds and cant afford bills"
Look who's talking about culture and manners?
The guy, today Feb 27, kept on calling me, and simply laughs when i shout back.
When I warned about my police complaint, he is not bothered for it, seems like Airtel and these agents have LAWS in their pocket.
I do agree, bills are pending but I had bills regularly since 4 years.But is this the way to recover ?

Now, I want to sue these and worst company Airtel and show them what they deserve to mentally,socially and personally harass me?
My sister will submit complaint to Airtel office for such personal,unauthorized,unreasonable and threatening call to her and thereby I am going to take legal steps ahead starting from this Consumer Complaint forum.

I have the callers's name, no and their few call recordings.
If anybody authorized from Consumer complaints or legal panels will get back to me for proceedings, I would like to get in touch asap.
