This number claims to be an investigative or lawyer office for a Mr. Washington. Mr. Washington will also claim to be a Mr. Robinson and there is a female who works with him. They will call you from this number and a 4023175060 number. When I demanded that they give me there agencies name, the threatened to call the cops on me, and within a few minutes they spoof called me from a police district in my city and claimed to be an officer Brown. They then called me from a number that was linked to a address near my home. Luckily the numbers that they have are not my business number, because I am unsure if they will continue to call. I have filed a police report in my city so if they do continue to call I only have to report the calls with dates and times they called.
