A caller from this number asked to speak to my wife. As soon as I asked "who's calling, please?", they hung up.  It's a scam in which they tell you they need a donation and tell thank you for your donation you made last year (even though you never made one). They call here constantly. I have reported them, but to no avail.
I tried calling them back so I could scream at them and tell them not to call anymore, but the number does not ring a phone when you call it.
