I called the number back after searching it online first.  They said that they were offering a 50% discount on an auto-club membership associated with my Petro Points Card.  I told them that I already had a CAA membership...they thanked me and wished me a good day.  They were actually very nice...well, the guy I spoke with was.  Now we'll see if they keep calling me or not though.

Same thing keeps happening to me. It was listed as Unknown first, but now it's listed as Long Distance.

I keep getting a call, but no one is on the other end. Very annoying.

CAA, sillies. Actually, I think it was Petro Points as affiliated with CAA offering a discount on CAA membership for Petro points holder. The woman calling didn't seem to know I already have a CAA membership so I suspect she got my number from my Petro Points card account.
Hope this is helpful to others. Relax, it's not the CIA!
:P

Does anyone know who this might be? answered a call to only have dead air on the other end, said hello three times, after about 10 seconds they hung up without saying a word.

No message
