Most useless car manufacturer / dealer

I am so disappointed in the after sales service offered by Hyundai South Africa. They have not responded to my previous report and also do not respond on twitter. I have had it with this brand. I want nothing to do with them anymore. The clever people at the branch at Wonderboom suggested that I take my radio in to CRS Audio who have now messed up my radio even further. After taking it out they told me that they could not repair it and didn't bother to put it back in. Now I am driving around radio less with a hole in the dash. All thanks to the referral at Wonderboom and the Service Advisor at Sandton who suggested that I take my radio to an external service provider. Where have you seen a car manufacturer refer you to some chop shop on a corner to fix their brand? Goes to show how little confidence you have in your own brand. I am still waiting for the service manager at Wonderboom to call me. To this day he never bothered to. HOW USELESS!!! I cant wait to get rid of this useless brand! Dont bother with them they will not help you ever with their own brand!
