Who called from 6467517865

I received one today from this number, but missed the call and no voicemail was left.  Unsure who this is.  Anyone know?

The same story, only one ring, no voicemail

Yup, one ring and they hung up. What's the point of them doing that?

I received one call from this number and was told I won some marketing promotion. I will get $100 gift card for Walmart and $20 Amex gift card. But I have to pay $4.95 shipping fee. And he asked for my credit card information. Then I hang up.....

I got the one ring and hang up too.
