Called and asked it I was my tenant. When I replied no the caller asked if he was in? I said he was out. I didn't tell them he was out in the next room. After checking here the number is now blocked.
Rec'd a call this morning. Came up on Caller ID as 'Unknown.' As far as I am concerned any legitimate company that really wants to conduct business with me would not hide their business name. I didn't answer. Thanks to these forums I now know I can go in and just block the number.
