Dude,  if you have a newer call blocker, block the area code!

If you don't have a device or phone, read up here on them here:

Thank you for the links.  I'm getting spammed again tonight by these same three numbers non-stop, once every 20 minutes more or less.  I've auto-blocked them on my phone so at least I don't get annoyed by the notification, but still it is aggravating.

You've reported several call times which are past the default hours for sales, debt collection, and fundraising, possibly giving you cause to sue the as yet unknown call source. You might want to answer a couple to be sure you're not leaving damage award money on the table.
