Airtel — Reg: Wrong billing in my Airtel postpaid connection

Address:

Bangalore, Karnataka

Hi Team,

My name is Hareesh And my number is : [protected], I am using this from two years, All of sudden Airtel started doing wrong billing and i called then
several time to remove what they charged excessively(Some WAP services they are charging 350rs per month).

And i said them until they remove those charges i would not pay the bill, They have accumulated all the amount and after 3 months they stopped my services.

Now the funniest thing is that even after they disconnected my number they are charging 800rs per month as bill.

And they started calling me and harassing, Calling all my friends and family mobile numbers and asking and explaining that they will impact in my cibil rating.

All of sudden again today they are calling my friends and saying that they are from coriar services and asking for my address.

I do not understand what kind of ethics that they follow.

Can any one suggest me how to proceed from this situation.
I have all the bills.

Thanks,
Hareesh.L
