car lease drama

so its been 48 hours and the supervisor from the lease department of chase bank has never called me back. i called them and got a man named don in the lease department. he was equally hard, illogical, and an asshole as mark. he said i owed over $30k and would be prosecuted in the court of law and reported to the irs (returning a leased car has something to do with income?) etc etc. once again i asked for a supervisor and he was reticient to allow me to speak with one. i asked three times and was finally transferred to a voice mail where i left another message. does it seem logical that because i owe six months of a lease, about $3000, that i should pay them $30,000+ ~ does it seem logical that they should expect i would pay that? i said to don that there must be some reasonable way this can be resolved. he said no there wasnt!
