Calling my DNC registered landline, initially blocked then called back immediately on a different number that got through. The caller ID on the original displayed the number 480-257-7667 and Martin Management. The caller ID on the next call was 608-371-6666 and again 608-371-6666.  It was a timeshare scam. They were calling in an attempt to help me with "my" timeshare (I don't own one). They said they would take me off the list. It seems highly doubtful, I guess well see.....They also call from 972-456-9190 Martin Management, same timeshare scam
