Poor After Service

My mom bought me a new car year 2015 at the Heidelberg branch. That was the biggest mistake ever, leaving all branches to this useless one. The car was new and ok however the documents were incorrect, I had no service plan to start with and the VIN number on my documents was for a vehicle that I don’t know. I had to phone MFC to fix my own paper work, the dealer could not care. I phoned them and emailed but no assistance. Today I want to claim on my warranty policy and guess what? The information they have if incorrect! VIN number and engine number do no match with the car I took to the dealer. I am sick of KIA and would never recommend anyone to purchase especially at the Heidelberg branch. Poor, poor service!
