Came up as SNJS West CA on caller ID. Tried to call back but got the "this number is no longer in service" message when I did! It makes sense that this could be CA PAL as suggested by BUDMAN as I made the mistake of giving them some money like 6 years ago. 9 AM on a freaking Saturday!
I answered. There was a pause. Then a recording that said, "Due to a technical difficulty on our end we are unable to speak with you personally. Thank you. Goodbye."
