Called 6-29-16 at 4:23 p.m. Caller ID showed 1-720-851-9900. No message was left.  There would be no need for this to be a long distance call as indicated by the 1-xxx-xxxx. We get sooooooo many calls from locations, names of people we don't know and businesses we have never heard of or conducted business with. Since these scams have not been effective on us, now we are getting bombarded with multiple daily calls from 1-xxx-xxxx. Bet these low life criminals consider themselves quite clever with their spoofing tactics, but of course they're not, they're just too STUPID to gain legitimate employment!!. We never answer any of these calls.
