Hi all,I am a user of Dataone 500 since June 04. To my great inconvenience, they had not been billing me regularly all this time - and 2 months back, slapped me with the bill for the entire period from June 05 to December 05. I paid the 6000 odd rupees phone + dataone bill, albeit with some difficulty.Now this months bill is 7000+. Telephone charges are minimal. It apparently includes 'Usage charges' for July, August and September, which has come to the tune of 4500 rupees. I am completely sure I did not exceed the 1 GB cap in my normal usage time (ie, 8 am - 2 am) - I used to collect the data from the Dataone site, and save them in excel sheets - separately records between "8am - 2 am", and free records between "2am - 8 am". Then I used to use excel functions to add 'em up - I did this till december, very painstakingly. For neither of the 6 months (july - december) did my normal hours add-up for the month cross 1 GB.But the sad part is, after getting last bill (the 2 months back wala) I thought the necessity of storing the records have been served, and I deleted the excel sheets. That bill didn't show 'extra charges', and charged 'rent' till december. I thought, since the bill was till december, and no extra charges were asked for over the rent, the issue was over at least till december - I did not have to save all those excel sheets anymore (I made them as proof in case some goof up happened). Stupid me.Now I have this HUGE bill, which has wrongfully charged me for 'extra charges' in July, August and September (August and September in 15 day blocks). And I dont even have the proof in my hand, that I had so painstakingly made. I am sure they have wrongfully added the night free usage to get to this total - and I need to fight this out. The problem is, I have exams in May, and this additional tension is making me wild - but nonetheless, I cant pay the money, or rather, I cant pay wrongful money - so the fight is necessary.Has anyone experienced such a thing? How do I proceed here? What if BSNL shows me some records which say that I 'did' use as per the billing (which can very well happen, given its such a messy organisation)? And what if I deny to pay the bill should they ignore my claims (which they might)? What happens then - ermmm....court order or something like that? :angry: Night charges were free in July, August and September 05 too, right? I am sure they were - but I cant find a proof on the internet which says so - like, maybe a webpage made before that day, or a newspaper advertisement before that which claims so. I asked ALL the BSNL people then to clarify - right from people at the office, to the guy who came to set up the modem - all said yes, its free at night from July. Any help would be greatly appreciated. Thanks in advance.
