Six or seven months ago, when online was going very, very slow, I also started mailing in 90 day notices. While it was taking 10 or 12 days for online to work, mail was even longer. I did always receive replies from both eventually. But the mail would take almost until the next 90 day was due before I received it. 10 or 11 weeks. Nowadays, online works okay. Just a couple of days at most. I would go back and try online if I were you.
