Called my cell phone and when I answered the man said his name and the name of a company he was calling from so rapidly I didn't catch it.  He didn't even try to verify if he was speaking with the right person but went straight into trying to collect a $1,000 debt I supposedly owed.  Refused to tell me who and when the debt was from.  I hung up and blocked the number.  This is almost certainly a phishing scheme.
