Consumer Redressal

I\'ve recently ported my mobile number 9821804311 from Loop Mobile to Vodafone on 15th May 2013. My bill for the period 11-10-2013 to 10-11-2013 amounts to Rs.9832 which is way too higher with respect to my previous 5 bills. The bill amount is completely charged to internet usage and no call charges. I\'m completely confident that the charges incurred on me are faulty and I\'ve receiving frequent calls and messages from them threatening to pay the bill or else the service will be barred. Already they have barred my internet service since past 20 days for which I\'ve already had several discussions but all in vain. I\'m extremely dissatisfied because i can\'t bear the loss of my mobile number as its linked to almost all organizations I\'m a part of. I finally decided to write to you about the problem. Please help me out.
