Calls during late evening

Received a phone call saying I had donated last year and they are going to mail me another donation form.  They did not asked,  just told me they were going to do it and if I wanted to donate more. I do not donate to this organizations that helps Veteran ( if I did it had to be a long time ago).  When I said I could not help this year he said he would but me down for the $12.00 donation and his supervisor was going to confirm my address- they did have my address.  When I told him I could not promise I would pay it he just hung up.  The caller ID did not have the name of the organization and  the phone called seemed suspicious.
