Sorry for my reply. I'm only F-Secure user (their home solutions).
I think this not clears the matter -> at least, with Community side.
Maybe good to contact their direct Support Channels (and 'designed' channel for subscription discussions):
Should be possible to use chat or phone-support. Then your information can be useful to sort your trouble (it is unclear what kind of trouble there).
Of course, if you have not already done that. Also, maybe good to edit your 'partial' information (because it is public website -> so, if this can be critical to you -> such things can be visible for someone else and usually it is 'unexpected' result).
