I'm pretty sure this is the first time this number has appeared on my call display but the recorded message warned me that this was the third time they have tried calling me and it may be the last chance to get lower interest rates on my credit cards!  Oh dear!  They said to press 1 if I had an American Express, Visa, Mastercard, or Discover card.  Who doesn't have at least one of those?  Or press 3 to be removed.  I just hung up.  I didn't know what pressing 3 might actually do.
