Airtel — tremendous network issue

Address:

Thane, Maharashtra, 421302

I am mehul maru, staying at a/201, arihant dham, house no. 296, arihant nagar, bhiwandi. There is no airtel network at my home since last 6 months.
I am airtel user since last 9 years.
There was no response from airtel customer care, i was surprised to know that they marked complaint resolved without any resolution.
Is this the service of airtel???
I request for final time now to resolve network issue at my home asap
