They just called my house asking for my mom.

calls from 312 423 7539 says my street then asks me to verify my info to him. i told him not until he verifies my info first. african american voice trys to sound intimidating and claims to be from harris and harris. could be legit could not either way you need to confirm to me who you are. never said he was a bill collector. either way this almost always happens after i signed up for google twitter or facebook. watch your privacy settings and if they ask to speak to you and you say who you are you have already verified yourself its now up to them to verify themselves either way don't give them anymore info than needed and never trust who is on the other end. if its real than have them mail thier info to you and do your research. unless you know for sure don't let them push you around

Keep getting calls from this place saying " Hi, this is Henry Hoover with Harris and Harris" when I stay on the line nothing happens. When I call back noone answers. Dont know but have read alot of negativity about them.

These folks called my office.  I don't have any business with them.  I would never do business with anyone like this even if I had a debt. The name "henry hoover" is likely not anyone's real name.  Exercise caution. Ask for a landline direct dial return number, a physical address, send a certified letter, request that a person with a first/last name, a signature, and a direct dial number respond to your query.  Legitimate people do not conduct business this way.

This is not a scam. They are the collection agency for City of Chicago parking and red light tickets. They are the ones who boot your car now when you don't pay tickets.
