Whoever is behind this number most likely is a phone scammer, and the first tip-off is that my Caller ID indicates "No Name" or "Unknown Caller" or "Private Number"...
I don't answer those kind of calls, because in all likelihood it's some kind of scam...
Anybody I want to or regularly talk to, their name shows up on the Caller ID - otherwise they can take a long walk on a short plank!! I will chum the water first...
