Kia Motors Finance Lease End Disposition Fee - Told Didn't Need to Pay & Then 2 Months Later Wanted Full Payment in 15 Days Dallas Texas Nationwide

Recently I lost my job and was leasing a Kia Forte Koup and paid each month on time for the ful term.  I don't do much driving so the car had less than 2 years of milage.  When I turned it everyone at the car lot couldn't believe how nice the car looked.  I told the salesman my situation and how I bought a $3000 used car to get by for awhile until I knew more on what the future help for me.  He in turn said there probably wouldn't be a disposition fee because of how nice the car looked.  I said thank you and when things turn around I hope to be back!

So almost two months go by and in the mail a bill for a $400 disposition fee plus $36 in taxes (which are not disclosed what they're for?)  and the they wanted full payment in 15 days.  I called and of course KIA & KIA Leasing are two different companies - so what the salesman says means nothing.  I discused my situation and I even offered to pay $100/month till it's paid off.  They told me the best they could do is 60-days from the billing date or it goes to collection.

Thanks for nothing.  Kia leasing obviously doesn't care about good customers and I'm never going back.
