Vodafone Haryana – Wrongful deduction of Balance

Vodafone activated hotshots ( don’t know what the hell that is) on my number on 17 march 2015 at 10:14 pm and deducted ₹21 from my account. When I talked to customer care they rudely refused me for the refund and when I wanted to register my complaint they put me on hold.
When I searched internet about such incident which I faced, what I found was there were innumerable number of balance reduction complaints against vodafone.
I think this is a general policy of vodafone to earn revenue through such filthy tricks. Vodafone’s customer base is going down day by day. And I have also applied for MNP.
