Unwelcome call on my unlisted land line @9:135 a.m. on 5/02/2016, There was no message left.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. 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.
