I was the Vodafone customer for the past 10 years, now I have switched off to Airtel. There are some problems. Till the Hutch holds the network the service was good, easy access to customer care, Excellent network and very good tariff. The Hutch only introduce the Chotta recharge and they had real intention to give good service.
From day one, we have bitter experience with Vodafone. I personally iltreated in Vodafone Kilpauk Customer care by a lady executive ten days back and she just behaved like as if she is working fish market.
