I think this is mostly true .Except , when I called earlier and spoke to a rep at SBTPG she said they were releasing refunds in batches all day, even while the website is down .The website is down just because it couldn't keep up with all the traffic.
So the website being down won't have anything to do with it. It just depends what batch you're being released in .
Also TPG is 3 hours behind Est not 2. So it'd actually be 7 here when the site is back up.
