Called at 9:15PM. I let it ring.

It's a survey company. Offering false amounts of money for doing surveys. They are listed all over the country. They were sending me emails but when I tried to respond it came back with nothing. They are a shady company. The BBB has a ton of complaints for every branch they have.

Called at 7:13pm on a Saturday night.  They have no life and they're ruining mine!!  Let it ring, no message.  Now blocked.  I thought SPAM was bad but it goes into a folder without bothering me unlike this nonsense.  Phone ringing at dinner time, while entertaining, when someone is sick.

Receive a number of calls from this number, but no one ever speaks.  They hang up after 20 seconds or so.
