@Intrepid,
I called just the main number today, as I deleted out all the messages. I got a customer rep and while she was searching for Elmer I said I'd assume Elmer hasn't been making his payments - she said "Bingo!" I told her the only Elmer I know is Elmer Fudd which she completed the punch line and "he's out hunting rabbits."
I did let her know that this was a new number for us - only a few months old; which is true and she said it was probably an old numer of his. Quite a coincidence as Elmer shares the same last name. I didn't tell her this as I didn't want her to have any of our information - I just stated there is no Elmer at this number.
Hopefully this solves one of our many many calls we do not receive.
I'm also guessing that the 6pm the other day was so he wouldn't have his car repossessed.
