Who called from 7082020173

Unwelcome call on my unlisted land line @ 9:27 a.m. on 8/10/2016.  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.

I don't know this number, blocking the call.

I received a call at 9:00 am on Saturday Feb 25.  Caller said he was from Danley home improvements and asked if I would like a rep to stop by my house and give me an estimate. Of course this number is now blocked.

Scammers called about 8am. Didn't answer, no message left.
