Also rang my cell yesterday in the evening. I don't know anyone in this area code so I didn't answer. No voice mail left. Either a wrong number or telemarketer/scammer of some sort.
I called the number back and got a recording... Al representatives are busy now. It did give me an option to put myself on the do not call list so I did theta!
Called my cell so no CID. I didn't know the number so I didn't answer. I NEVER answer a call if I don't know who it is from. If it's that important, they would leave a message. Since none was left, it can't be that important.
