Hyundai south africa

I have a warranty claim dispute from Hyunday south Africa. I have tried for weeks to get through to any one other than the customer care desk. Go through eventually and the lady made a case and said she will get back the same day. Two days later im trying to follow up , on the phone for hours but either no one answering or when they transfer my call it goes offline eventually after 15-30 mins . This is shocking service and dont have a car to get to work and back in the meantime . Hyundai south africa are responsible to provide service as i am responsible to pay then lease end of month right ? Sounds like a one sided relationship this
