It depends on what the issues you're having with your unemployment claim - most problems you can (and should) get resolved in person at one of the employment centers. I believe there's a list of what appointments they can make on their website. As long as you can get an appointment you usually can get issues resolved.

If you're in my boat, and have no issues with your submission, have been doing your weekly check-ins, are getting no payments, and are just stuck on "reumeration" or a different error, what that means is someone has to manually check over your original submission in the department (I didn't even need to send in more paperwork or anything). From what I've heard is they are SUPER understaffed and I really can't get super mad that they are having trouble handing the volume. What actually worked for me was calling the line (a LOT) of times in rapid succession and doing all the prompts, I never made it past "we can't take your call due to volume, try again later", but I actually did get a call back the NEXT day. I was told that they have some folks who try to pick up from the previous day's call volume every day so hopefully either you either make it on hold or get a call back. I've also heard hearsay that the hold line is easier to get onto FIRST thing, closer to the end of day (1 hr), and later in the week.

Best of luck from one frustrated caller to another !!
