Airtel — incoming calls barred since 15th aug

Address:

New Delhi, Delhi

Dear sir
My incoming calls has been barred on [protected] since 15th aug.
I brought to the notice of my service provider airtel but got dates from resolution as 20th, 22nd and at the earliest as the date for resolution.
With that the executives are very rude and abusive.
It is making me suffer lot of losses.
Please help me in getting it resolved and please look into my losses too.
