I missed a call from this number and they didn't leave a message so upon Googling their number I landed here and, based on everyone else's comments, I would conclude they're one of those evil credit card scamming scums. May they go to hell.
Just received a call from this number: caller ID says it's a mobile phone associated with a Vanessa Guia. I didn't recognize the name or number so let it go to voicemail, which was a hangup.
