Terrible customer service

I have complained on numerous time when booking my car in for a service that the Radio is not working properly and just does it's own thing. My car only has about 60000 on the clock so its a fairly new car. On all occassions nothing was done. This is frustrating and i will inform all of my friends and family to NEVER use this branch for anything as their cusatomer service is pathetic and so is the service agents.<br> <br> My Service book has been lost by this branch only as i will never take out my service book from the car and i still had to pay for it.<br> <br> I will never deal or buy anything from Hyundai ever again.
