They called every single day for months on end and never left a message. I called them back and got a recording saying they were MBS (guy talked so fast I think this is what he said) Communications and that they were a fund raising firm for national organizations. I have now blocked their calls.
Got call about 7pm tonight from this # for 1st time. Hung up when rolled to v/m. This is 4th call in 24 hrs from unknown callers. Even though on DNC lists, also 2 calls to cell phones. This year has been crazy with scam/spam calls.
