Called my office landline, which is for a major mutlinational.  I was not in and they left a voice mail with a recorded message about lowering my credit card interest rate.  Obviously a phishing call for a credit card scam.  (The message had sort of a British accent).  Called the number back and got a recording that it is a non working number.  Seems like a the caller  may be from overseas and the number is spoofed.
