"All the spam flood clogged our Tor server, so we're having to defrag the 160gig database it's on. Will take a while. Sorry"
I went into settings and stopped using Tor and was successfully able to make transactions. My past transactions that did not appear on the Blockchain, have disappeared and my balance is correct.
Twitter really does seem to be a very good place to get CS as no company wishes to give bad publicity in such a Public Forum.
