I just wasted 4 hours trying to fix a problem. I dialed a Skype-to-phone number and got "Account blocked". I spent the next 4 hours chasing down rabbit holes suggested by the virtual assistant and her evil minions. I finally lied to the 20 questions and said the problem was with Windows, which got me to a human, who finally connected me to a person named Maurice, who made a simple suggestion that really ought to be listed as a cause in your knowledge base -- I use a VPN. Apparently it picked a poisoned IP address. All the other suggestions were irrelevant. I turned off the VPN and my call went through just fine. 5 stars to Maurice!!
