This is the message which i got yesterday. The same i got last month also but left it because without knowing might have pressed any button.
But this month am same i have not activated any pack but 90 rupees has been taken from my vodafone number without my confirmation. Even i dont know wat is zone pack. But now am sure the people working are activating packs themselves and charging.
Iam very unhappy with vodafone nowadays. I need my amount back. Please dont cheat ur customers and
Please return my money back soon.
