Virgin GSM Mobile — Balance deduction with false cause

Address:

Kolkata, West Bengal

On 26th feb 2014 I notice on my mobile that Rs.3.30 is charged for internet browsing. But I have data balance in my number. So it is not fair to deduct my balance. I contacted Customer Care executive. They are saying that I have clicked on some chargeable link! But have not done that. Only facebook.com was used by me. They are cheating their customers and refusing to give my balance back. Should I give my mobile number here publicly?
