Airtel — Airtel -network issue

Address: Mu-partewadi Po-eksar Tel -Wai satara-412803

We have raised complaint against network issue many times but they gives commitment only.
Every time they said we will solve your problem in next 48 hrs or next 3 working days but still now they didn't take any actions.
I faced network issues from last 6-8 months.
Also my neighbour raised same complaint to Airtel customer care through call.
