Vodafone India — 4 paise deducted every hour even when data connection is off in mobile

Address:

Chennai, Tamil Nadu

I have a Vodafone connection and my mobile is charged 4 paise every hour for data even when my data connection is off (Also i am using a Wifi to connect to internet) and when contacted customer care they are not answering properly and are talking roughly. I am very frustrated with their service after using Vodafone network for nearly 8 years now.Very bad support.
