Unsatisfactory delivery

My furniture was supposed to be loaded on Monday 27 July 2015 at 06:00 in the morning. The truck arrived only at 12:00 in the afternoon after numerous calls. They eventually loaded the furniture and were finished at 17:00 that evening. The furniture was suppose to be offloaded 06:00 on Wednesday on 29 July in Barberton. After numerous calls(AGAIN) we were informed that the truck would be in Barberton at 17:00. The reason is that they were held up in Nelspruit because the client there was not at home and they had to wait for the estate agent to sort things out. My complaint is that there was furniture of the owner on the truck as well and their priorities regarding client relations are poor. The owner's own furniture is more important than mine? In my opinion that could have waited until the truck arrived at the depot because,after all I am the paying customer.
