I just got a call from this number. I knew its a scam. I played it to see what they would say. I finally told thme that i was going to report to the police. They said they are card service. I told them they are liar and if they call again i will report them. I blocked them. I gotten other calls from the same nature. I block them but then another number appears with the same scam.
You might be surprised-there are a fair number of folks who only use their cells for "emergencies" and actually do not feel the need to be connected 24/7. And they get by just fine.
