Caller knew my name and said this was a personal business matter. Said the name of some business but said it fast, I asked to repeat and still did not understand. I simply hung up. I think they are "spoofing" the number that is shown on call ID. This call can be from anywhere.
This is a real debt collector. They are a company calling to collect money for a bill you have avoided to pay. This is a real company, they know the last 2 of your social which makes people uncomfortable but this is not a scam.
