Package Subscriptions: use at your own risk!

The package feature is not working & is very bizarre:
I run a free sign up and paid sign up:
a]free sign up, 6 gb bandwidth,, 30 days;
b]paid $$ 13 gb bandwifdth, 1 month;

a] FREE SIGN up ::once run out of bandwid(within 30 days) if upgrade its fine BUTif u run out again (again, within same month) the system wont top up further payment but take eventually the money from user), User complains, updated manually the user account with proper bandwiddth). I user dont complain I have to check manually every payment received( think about 6000 users)
b] PAID manly the same as above .
I guess it should remove the "Month" constrain in order to use "bandwidth" based subs properly..
Any suggestions?

Yes, please post this in the bugs forum.
