This is now fixed - sorry for the trouble it caused. Our SMS provider Authy was being marked as spam with Verizon. Thanks for your patience while we worked on this!
You and I both know this is false. I clicked the CALL me button, and I got a message saying "Sorry, an error has occurred, good bye." No spam filtering, no spam filtering at all. No replies from your support after 'this error will be fixed in a couple hours' either. It took over 48 hours for me to finally re-gain access to my account. This is after canceling 2 very profitable Bitcoin buys for no reason whatsoever. Biggest crap service ever. From now on its CampBX all the way, for me.
