Phone rings at odd hours of the day and night. No message is ever left. We figure it is some sort of telemarketing scheme, because telemarketers NEVER want anyone to know WHO is calling.
Got a call last night. Didn't pick up. Googled the number and found this site. I always Google the number and never answer numbers I don't know or hide their identity.
If you call the number back it tells you that you recently visited one of their affiliates and they have a gift card for you. It then gives you an option to "redeem" your gift card or to be put on the no call list. It is a scam, so I would click option 2.
