Vodafone India — Coverted to paid plan from free pan without notification

Address: Kolkata, West Bengal

I have 2 vodafone corporate connection. I was previously under plan 99 rental which was the benefit of 100 mints of any local call free. But last month my plan has been converted to 149 rental without notifying me and that plan has 100 mint of local vodafone to vodafone free call only. Hence, I have been charged for the Vodafone to other local calls. That means I have been charged for the other number calls and that happens without notification. This is one kind of fraud where I suppose to get free minutes but I am not getting and I have no information about that I will get charged if I make Vodafone to others local calls. My 2 numbers are [protected] & [protected]. Please look into this matter. I have checked with the other consumers as well and I have received same feedback.
