Well, I'm glad I am not the only one then.
I sent mine in on June 17th and it hasn't shown up online and my CC hasn't been charged.
I called RCMP today and the lady said it doesn't yet show up in their system and to call back in 2 weeks. She couldn't confirm if they had even received it. For all I know, it got lost in the mail...
I didn't sent it requiring a signature as I had a way to send it express without paying for it (through corporate mailing).
i sent mine via snail mail, and CFC received it 5 days later... Usually it takes about 20-21 days for it to be charged on your CC, than it appears online. Remember though, 28 day waiting period is mandatory, so they probably won't even touch your file then. But you said you sent yours in June 17th, which is over a month ago... So I'm not sure. Hopefully it isn't lost.
