Unwelcome call on my unlisted land line @6:51 p.m. on 10/05/2016.  I hate running to see who is calling. This is very annoying. I will block it, but really I can only block 250 calls and I keep getting 5-10 calls a day.This is crazy. Sometimes I delete a number from months ago only to have to re-block it. Some of them are the similar exchanges. Thank you for this site that helps us identify these spam callers.
