I keep receiving calls from this number but I do not answer because I do not recognize the #.

File a complaint with the FCC.
Telemarketers cannot call cell phones, if you get one, file a complaint with the FCC.
Also, telemarketers cannot call after 10PM, if they do. File a complaint with the FCC.  I used to work at the FCC, and they do go after these telemarketers, but there has to be enough complaints filed. 100 complaints is enough to be referred to the Enforcement bureau for investigation, but a complaint has to be filed.  Go to http://esupport.fcc.gov/complaints.htm  and follow the prompts. Or call 1-888-225-5322 and ask to file a 1088 about telemarketers.

Caller left no message for me either.

I got a call from them, too, and they didn't leave a message. I called the # back a few hours later and got an automated message asking me if I wanted my # removed from their database. The company's name (per the automated message) is WCA Offer Clearinghouse.

same here idk who they are! any idea .
