Got a call with ID of Seattle WA asking for me by name. He was from some sort of credit counseling and said that one or more of my creditors had been found guilty of unlawfully raising my interest rates. When I asked him which one he was talking about, he said he had a specialist standing by who had more information on that and could talk to me. I told him he was just fishing and hoping I would take the bait and that I was happy with my rate now and was not interested. I said thanks then hung up.
Just to mention they are still at it. In this case there was nobody there to speak to, so I hung up after a few seconds. The caller Id showed "Seattle WA"
Just an update. Received another call from the same number. As before nobody was there when we answered the phone. After 17 seconds we just got dial tone. The difference is that now the caller Id showed 'unassigned'
Another update. They called again, this time a live person was there. They asked for my wife, I said she was unavailable and they said they would call back later. Since they never bothered to say who they were or what they were calling about, I just added them to the call block list on my phone.
