Airtel — no coverage in ballard estate area

Address:

Mumbai City, Maharashtra, 400038

My complaint registered undercogcl[protected] is not resolved as per a sms sent. I have complaint 15 days back and was told it will resolve by 28th sept., long lapsed. Today morning i was told 48 hrs, n recieved a msg promptly that issue is resolved? Absurd to hear this. We are harressed that this is the only provider who has coverage issuses. I am in ntc house ballard estate which has no coverage when we enter the building. If i need to check messages it has to be on the road? I have lost a lot of clientale during peak season. Is airtel going to fill up this gap???
