I originally bought my certified Toyota Camry from you guys and while it was still under warranty I had problems with the transmission and acceleration and since it was still under warranty I brought it in for a diagnosis. I described the issue and I was told that if there is nothing wrong with the car I will have to pay for diagnosis fee which is 199, and so I accepted. 2 days later I have received a phone call and the service advisor claimed that there is nothing wrong with the car and I could pick it up that day and I went and discussed the issue again but he insisted that there is no problem with the car and so paid the fees and before I even drive 1 mile I could reproduce the issue. I went back and requested to talk to the technician who diagnosed my car and when we test drive it together he found the issue right away. and sure enough, it was a torque converter that was still under warranty. they replaced it for me and promised to reimburse for the diagnosis fee but it is been 8 months and has received anything from you. I contacted by phone and left a VM but never heard back.

Update: I'm changing the rate since James was really helpful, I got my money back once I talked to him
