Thank you for your message. I'm really sorry to hear your disappointment about the HAT Beta release.
Facebook and Calendar data plugs should work with all the Beta HATs, but I asked our tech team to contact you directly via email that you registered with your HAT. They'll email your shortly and they'll try to resolve your issues. However, if you're still unhappy, we can refund you the money.
I'd also like to apologise that it takes us a bit long to fix the issues. We don't have a full time team, but we're working as hard as we can. We believe that with our users feedback we'll make the HAT a very useful tool very soon.
Have a lovely day.
