Can of worms you've opened there piet2.
Infinite call is apparently no longer available to new subscribers - but if you beg and plead and insist, you'll eventually get it - apparently.
Do they cut you off for no activity ? --- I don't think so, some pople on this forum have been using it succesfully, and some people have been cutoff regularly, and some people that were cutoff have claimed their losses back because of the cutoff.
So - try to get it, if you can get it, use it, and if it cuts you off, insist on getting re-imbursed. It's going to cost you a lot of your time though. Good luck.
