Manassas Chrysler Jeep

I brought my car in on a Friday evening after my husband had spoken to a service representative explaining our problem with our rear tailgate of our T&C.  We had recently gotten our window shot out and when the glass people repaired the glass, the tailgate would not engage.  After a few weeks of driving around with the door taped shut we brought it to our mechanic who was able to hook it to his computer and get the tailgate to close but only when hooked up to the computer.  After another couple of weeks of not using the door but it staying shut because of the computer hook up by our mechanic we finally had the opportunity and time to bring it in to the dealer and see if they were able to figure out what was going on.  When my husband spoke to the staff member in service he was told to bring it in and during the day on Saturday if they found time to take a look at it they would and let us know what was going on.  On Saturday after we had to call around 3ish we found out they had taken a look at it and detected an issue with the assembly kit to the lift gate.  He said that the gate was in the closed position at this time and we told him that we would pick up the car and decide if we wanted to pay the $500 bill to fix the problem.  When I arrived with my husband and two children in the other car I paid my $110 bill for diagnosis and went out to my car.  There I found the gate was not engaged.  This was around 6.  We were told we could pick up after the service center had closed and there would be someone there for payment and to give us our keys.  I went back into the center and let them know that the car would not close.  At first the receptionist politely told me that there was nothing that could be done because service was closed.  I explained that I could not drive away with the car in its current state.  She then got me the manager on duty from the sales department.  At first this gentleman was not very willing to help until he realized the situation and went back
