Sent an invite about 36 hours ago to my friend, beta site says i used an invite and they've been invited, but they STILL haven't gotten an email. I just sent a invite to a different friend, they got the code instantly and are downloading now. But the first person i sent one too is missing out on the beta because of this and only response i got through live chat was "We see no key on their account and we have no spare codes, we're sorry for the frustration, can we help you with anything else?"

I even told them this is a widespread problem and it's all over the forums, their response to that was "all we can really tell you is keep an eye on the forums for updates." The beta ends in 2 days and still nothing.
