Vodafone Prepaid — Unfair charging for GPRS connection

Address:

Tamil Nadu

Vodafone had an issue with GPRS activation between 9th and 17th, April, 2011. I had recharged for 98Rs (Net Booster) on 9th April, 2011. The connection was activated only on 17th April, 2011. But they claim that my net has been activated on 9th itself and are unwilling to check if it was so. The validity according to them expires on 6th may and my browsing after that has been charged at nearly 80Rs, though i still have to close to 1.9MB unused.

A simple look into my net usage records between 9th and 17th will prove that i did not have net access on my mobile during that period. But they will not do that. never refund what has been unfairly taken.

Is there some way to make these people pay for such attrocities?????
