Vodafone — Excessive charge in post paid bill

Address:

Vadodara, Gujarat

My name is Huned ali.
My phone number is 9099xxxxx6.

I have been using this particular Vodafone number for the past one and half years.

In the previous month’s bill I have been unduly charged for the internet services that I did not use.

I gave a request to activate my 3G plan on 23rd November, but as per Vodafone’s records it was activated on the 26th of November 2012. The charges are being levied on me for using approx 2GB of data in 2G for a period of two days i.e. 23rd and 24th November.
What I do not get is that how can I have used so much data in a span of only two days over a 2G connection as I did not download anything. Also as per the data tracking device on my phone it shows that I have been using my data plan for only aprrox 120mb usage from 21st November to 21st December 2012.

I spoke to the customer care department over the phone and in person 3-4 times but there has been no positive response from their end.
They are not ready to accept that it might have been a mistake from their end and are trying to charge me excessively for no particular reason.

In hope of being served proper justice.

Regards,
Huned
