I get calls from this number OFTEN, and just got another one just a moment ago. I have never ordered anything from them, I have no pee-nuss!! I did not answer, and they left no message. ...Oh, and same here, the caller ID read "US Cellular". I should answer and ask them for a new phone. ;)
I called the number, it is a pharmacy in Canada. They speak little English but as far as I could tell they know nothing of these calls. It's phishing, ignore it.
