Rachel @ card holder services.  don't usually answer calls from numbers I don't know but it was local and people at camp tend to use their cell, not the school phone so I thought it might be about my child.  sigh  Should have known better.

When I first started getting these years ago (landline), I tried to get them to tell me where they got my number.  They said, 'from your bank'.  "which bank would that be?"  "well, your bank of course."  Since I had, and have, zero credit cards I knew it was a TOTAL SCAM.  Told them I had no cards and they hung up.
