Tata Docomo — Incorrect usage of internet

I am using a limited Tata Photon connection, and usually i use around 1 hr a day only. But my recent day daily usage meter shows a very huge usage. Especially on 29-DEC-13 it shows an usage of '1034 Mins'. But i never used that much minute

I send many mails to customer care to send me the detailed usage list (that includes the date, from time, to time, etc). But till now i didnt get any proper reply on this. I started the mail track on 31 Dec 2013

If i really require a high usage, simply i can change my plan to unlimited (there is plan for Rs. 950 per month). But now the current month bill was raised to Rs. 4499.

There is definitely a software issue at their side
