Called on a very bad VoIP service stating He was with Microsoft Azure.  Interesting, I'm a certified Microsoft Partner, they would have no reason for calling me unless I call them and I have *most* Microsoft support numbers.  If a so called "Support department" calls you from a local number(especially on a bad voice call).... HANG UP and report them here and to the FTC(?{need to look that one up}).

Sad, seems to get any work done, one has to block out large block of numbers or have a Whitelist calling.
