Bad delivery service

Try to understand why when they order it takes 3 days to deliver parts from KMSA distribution that's in sandton not far at all. This company delivers bike and they tell me they don't collect from a distribution company very strange in deed so this company don't lift a finger to collect parts at all. Another thing I spoke to the distributor and they explain that they can give me the parts if the dealer gets paid and they inform the distributor that the client is collecting the parts that is no problem. So me client must wait 1 week for his parts and his bike to be fixed will take longer as parts take long.
