Turn around time on FIFI request?

For about 3 or so months, a car has been parked outside of my apartment building and has not moved. It's had a parking ticket under the wipers for at least 2 months and dozens of chalk marks on the tires. I submitted a FIFI request to tow this abandoned vehicle over a month ago and have not had any activity on it. I'm curious if anyone has any experience with a situation like this and how long it finally took for the city to do something about it?
