I have written reviews for many companies and majority of my reviews are either a 4 or 5, which reflects exact the experience from the vendor. Prestige Toyota was my favorite till I bought my Sienna from them. I chose the car from online and it was exactly as described. The headphones were missing and the wonderful sales rep arranged a pair of new headsets within a week. However, they have a $500 deposit policy to hold a car. Which I paid as soon as I saw the car online. Then the drama started. The finance manager said it will be reimbursed and written in the paperwork. I was supposed to get back within a week or less. Long story short after numerous phone calls and trips making to the dealership after more than a month this still not resolved. The rep said it's not in his hand, talked to someone else. She said the will be ready in next day (which is a month ago)!!!!!!!!!!!!! I need to know who should I contact to get it back. It's very unfortunate to deal like this unprofessionally for resolving a matter that shouldn't take more than 2-3 days.
Update: I just got the check in mail, thanks(it took a month). For me, the reputation for Prestige Toyota is damaged for the frustration I have gone through. However, I'm raising the rating since they solved my issue.
