The caller ID was Health & Ed Serv (Health & Educational Services) so I made the mistake of answering the call. It was a robotic voice telling me that I had recently inquired about lowering my interest rate on my credit card. What that had to do with Health & Ed Services I have no idea, so I hung up. I call the number back and got a message saying, " this number is no longer in service". Blocking this number right now.
