POOR HYUNDAI SERVICE FROM UMHLANGA AND CUSTOMER CARE.

My auto i20 is doing 21000km and gear is now stuck on reverse. Called roadside assist and they towed my car on christmas day. I was promised that the dealer the car gets taken to would call me an update me. I have not gotten any call also had no idea where my car was taken. After calling roadside assist again today , they tell me its in umhlanga. I then called them on 3 occasions and no one knew what was wrong with my car. I tried asking for quinton who is the DP and got told his unavailable. Asked for Sham the services manager got told his on leave. Asked for the foreman got told his on a test drive. I am utterly disgusted by the poor service and i can assure you that when my car is out , il be selling it and buying another brand. Hyundai your communication s****s are below average and your car for juat doing 20000km im shocked that it has to alresdy be in a workshop. I called hyundai customer care today for about 28min and its just puts me on hold. Its sad that your grear advertising and sales pitches dont come close to the actual car and service you receive.
