Airtel — airtel service pathetic in pune - poor customer service

I have been trying to reach customer care for my poor data connectivity for last 1 months, but your customer care team is pathetic, they are not able to resolve this.

Today i was told by jaswinder (Sr. Customer specialist) @11:15 am, that there is an issue with tower at my area, fixing this may take 90-120 days?
Is this how you do business? After a consumer is buying project, you are saying there is issue with tower and you can not use for 3-4 months? Is it justified?
