Vodafone India — 3G Internet charges

Address:

Kolkata, West Bengal

So i recharged my 3G internet pack of 42 on the 7th and it was suppossed to last a week. But the interesting thing is i used Wifi for all my activities that day and guess what when i checked my internet was already exhausted. Trust me when i say i didn't turn on my net for most of the time that day and i was shocked that an internet pack which is suppossed to last you atleast 3 days finishes off within 3 hrs. And you know the charges are really high. If i am on facebook for like 5 minutes, half of my net pack is already gone. I need an answer.
