Someone's been filing for unemployment under my name and ssn and I cant get ahold of anyone to change it

I'm a 20yo college student attempting to file for unemployment in MI. I entered all my information into the unemployment website, and someone else popped up from my social security number. It looks like they were denied a claim in 2017. I have tried calling numerous unemployment lines and tried the online chat, but all say to come back at a later time as the lines are busy.

I don't know if my identity has been stolen and if I can get this fixed in order to file. I have no idea where to even begin to get this taken care of. The unemployment site gives me their full name, address, and phone number so I know exactly who it is, but who do I go to? There is no fraudulent activity in my bank accounts as far as I know, but I'm concerned that I wont be able to file. I have had to use my ssn for job, school, and taxes all since 2017 so I also don't know how this never got brought up. Please help!

UPDATE: I have completed my filing successfully and have changed all the MiWAM information to my own. The only information left from the other person is the actual name, as they have asked for legal proof that I have changed my name (I haven’t). I plan to contact my bank as well as trans union for any information they can provide. I will also continue to harass the unemployment automated menu to try to speak to a human in order to get that name corrected.

Thank you all, this has been extremely helpful!
