KIA SA

How is it possible for no branches in the Kia side in SA not to have a wheel bearing in stock in SA, Look i love the service from Kia in Springs and Prudence is the best - with the new foreman - but how is there no stock - now i have to drive for 3 weeks on something that can positionally cause an accident - as the part will take 3 weeks to get here - this is not safe nor good service from SA KIA
