Address:

Gujarat

Hiii...
I've been using airtel broadband internet with the landline no [protected] from Oct 1 st 2012.I've been misled reg an offer and been charged an addtional of 300/- for the same.When i called the customer care,they said that the offer is valid for the new connections taken from October 10th 2012.But the customer rep,who has all the req data abt my connection date,tricked me into accepting the offer n made a fool of me.All abt "Airtel being the no 1 customer service" is farce
