[Resolved]  MTNL — No bills are sent but security amount is required....

I subscribed and got new land phone at my residence on 15.03.08 and since then received nil bills from the mtnl new delhi for c/a [protected] (Full phone number is not given here) and paid the bills in good faith through internet.
The authorities have no problems at all despite my emails and reminders countless times from top to toe.
Then how the mtnl claims to be best despite having no setup for such plights and also charged one instalment of security(Refundable) despite advt in the times of india dated 12.03.08 that no deposit is required.
Even no reply has been sent in this matter as to whats happening?Except one formality letter with no details.
What a great pity...!!!
