Unemployment notice

Got a note from unemployment office announcing they will have a hearing on reinstating my unemployment benefits. Guess I need to inform them that I got a new job after receiving my last employment check. Plus the note threatens the possibility of overpayment and I may be forced to pay back some of my last unemployment benefits because they didn't do their job the first time. Nice. If my mohter was not paying my bills I would be living on the street in a cardboard box and these people threaten me with overpayment. Is it just me or is unemployment more burden than benefit?
