You're conflating a few different plans here -- "Standard" and "Advanced" are for teams only (minimum of 5 people). The only paid plan available for individuals is "Pro", which no longer offers TFA.
Looks like you were already on the business account, not an individual account, which is what we are discussing.
Hmm, I have no idea then. I just renewed my $99 personal account a few weeks ago. Not a business account from what I can tell. Invoice: http://imgur.com/eUpsaem
