Airtel — incoming & outgoing call can't receive

Address:

Thane, Maharashtra, 401107

I am not receiving any incoming calls & Outgoing calls from last few months and sometimes it suddenly starts working.

But from the last 2 weeks it stopped all incoming call and have not received any call on my airtel number.

I have tried to contact customer care but every time (I have called & informed my issue to them total 5 times now) they tell me the problem will resolve soon, but no action nor any return call I have received from customer care so far.

My address is B/304 Chnadresh Abhishek, Lodha Complex, Mira Road East.

Please resolve this issue ASAP.
