Horrible rip-off! Rear driver side door wasn't op...

Horrible rip-off! Rear driver side door wasn't opening from the inside or outside. I made an appt. at 10:30 for them to diagnose & fix. After 2 hrs they still had not looked at my vehicle. When speaking to someone, they told me i should've made an appointment. I told them, I did make one!! 5 hours, they charged me $120 to "diagnose" my vehicle. Basically, they told me they can't get in the door and could only GUESS what was wrong. They quoted me $2100 to fix without even knowing what was wrong!! I brought my vehicle to a local shop that fixed the problem for $225 (including parts & labor). Don't waste your time with these guys, they're not keen on customer service or keeping customers. I won't be buying another KIA ever again!!!!
