Post Paid Subcribers - Last Bill Date?


I just want to know the last date when the bill was issued which would be july this month by tata for postpaid accounts.My net connection is down from 14th and have asked the same to not bill me for that period. Strangely i have not got the june bill along with july. almost 50 days since i paid my last bill.Just wanted to know whats happening?moreover, whats with their pathetic new interface account. It shows i downloaded 10GB in 1hr on 1June 2006. I wish it were true though.
