Great car, Horrible service

Vehicle was running perfect before the 120k service. as soon as the service was completed it started to over heat. i took it in twice and was told that it was my radiator cap. on the third time i took it back in they said they will check it again, this was early in Dec 2015, half way through Jan 2016 i still dont have my car back and was forced to hire a vehicle at my own cost.<br> i have mailed the worshop foreman/ dealer principle and not a single person has responded to me.<br> <br> Needles to say even though i like the car, i will be getting rid of my hyundai as fast as possible.
