I've been getting calls from this number for over a week, twice a day. I had my husband answer the phone and they said they were Black Hills Energy. Black Hills Energy shows up as Black Hills Energy on the caller id. The caller id for us also said Austin Graven. Pretty confident this is a scam number so it's best to block and ignore if possible.
Call coming from 720 251 2285 claiming to be from manufacturer of security systems. saying your with adt correct and then we say no and they say well which one,, none of you business we reply then another call from another number.
This company/person has been calling every day for more than a month. Austin Graven on caller ID. No one on the other end of the line until today. No explanation why no one ever spoke. Marketing company that wanted information. Asked them to not call again. Very rude.
