KIA Witbank

I took my vehicle to Kia Witbank to replace the fuel pump for the second time in 4 months last Friday. After the repairs my hand brake is not working so I took the vehicle back on Monday. The workshop manager, Antoinette, promised to phone me on Tuesday to make arrangements to get the vehicle booked in at a branch closer to my work and since then I could not get hold of her. I have tried numerous times to call her and left several messages, but I don't get any response. In the meanwhile I am driving without a hand brake. I will make arrangements with another branch today and will rather take my vehicle elsewhere for repairs as I have had this same problem at Kia Witbank previously where the people assisting you promises to get back to you but then they never do.
