called me today, no idea who it is either...

keeps calling daily up to 10 - 12 times

No messages left today or on 13th when they called.

The number is from Toyota and Lexus Financial Services.

I've been receiving calls daily from this number, no message left what so ever.

Can anybody tell me..... WHO are these people? What kind of company is this? and What can we do about these people that is calling from this number?

they are a nuisance.  I get the same thing every now and then.  If they don't leave a message I am not answering.  It must be an automated phone system

This number calls a lot, if it is Toyota Financial I do have an account with them, but my car payments are current, so I don't see why they would call me 10 times a day!!!!  No one is there when I answer either!

I also have an account with Toyota Financial.  I am one payment behind, but technically only by about a week.
I have been getting several calls per day from them for a few days, usually in pairs where they call (and I do not answer) and then they call right back.
I have not been answering because of the conversation I had on the first call (which I did answer):
They asked for me, and I said "Who may I say is calling".
She replied "Oh, this is Jamie".
I could never get anything more than that name out of her.  She just kept asking for me, and saying that she was Jamie, as if I know her.
If this is indeed TFS, and they do indeed need to speak to me, they need only say "This is Jamie with Toyota Financial Services."
If you aren't going to admit who you are, then I ain't gonna talk to you!

you get one day late and they call ten times aday
