I stopped using SCF because issues such as this never get resolved - it's not an easy fix like a parking violation for example. I suggest you email the alders, and dpw, and copy the mayor's office. Still, no guarantees anyone will address your issue. I know from firsthand experience - I've been emailing DPW and Parks and the Mayor's office for weeks trying to get them to commit to cleaning up the park. I've even attended the last 2 Parks Commission meetings. It's a real challenge.
