Have you ever face any issue with Boradband Billing? My pan is 299 plan and they always keep on charging me with extra downloads which I never do.
At Rs300/month, I would not be surprised if this amount covers the connection only, but no data - and if it does cover some data, it won't be very much, and therein may lie the problem.
Can you point me/us to the webpage where I/we can find details on the plan and advise appropriately?
