I got a call from this number at 4:51 pm. i tried calling back but got a recording that said to call back during normal business hours and a customer care representative would be happy to assist me. No name, business or otherwise, was given, and it still wasn't quite five o'clock. Legitimate businesses aren't usually so mysterious.
The Do Not Call site is a good one to report unwanted calls from LEGITIMATE telemarketers. The DNC list does not cover calls from criminal scammers & spammers. To report those, visit https://www.ftccomplaintassistant.gov/
