Airtel — Incorrect Download Data Tracking

Address:

Mumbai City, Maharashtra

I am currently under the rs.1500 broadband plan,which entails me 4 mbps connection until 30gb,after that the connection is reverted to abnormally low 256kbps.Now,the problem I've been facing is this -

1.On the 10th of July,I got a message on my mobile phone that I had reached 80% of my allotted data usage,which was calculated to 24gb.Later,I checked my dsl usage through the airtel.In website and I consciously decided to stop download anything (even minor files) for a couple of days.The next day (11th July'2012) I checked my usage on airtel.In again,and I has allegedly downloaded 27gb out of my allotment.Considering I barely switched on my computer for roughly an hour,I was shocked.I DID not download a single file like I had decided.Yesterday,I was busy the entire day so I didn't switch on computer at all,until right now and I had supposedly downloaded roughly a gb again..Now,I do have a wi-fi router,but I have a powerful enough password,and almost every neighbor in my area has a wi-fi connection and I've checked my router page and I found no rogue connections at all.Plus,I recently opted for a much more powerful password encryption.Hopefully someone from the company will read this and rectify this as soon as possible,since this is some data calculating error from their side.
