Who called from 7043368618

Someone at this number called today and left a 1 second blank message.  I have no idea who this is.

I got a message from this number: it said i had something overdue, and it sounded like they said they were "A.G. Kryder"???
i do not have anything overdue....

Could be the library????? I "answered" but didnt speak and I didnt hear anybody in the background.  OR it could be a call from MJenkins Air Conditioning, they call me a lot.
