Very poor service, I regret buying parts from those branch

Very poor service, I regret buying parts from those branch. I bought parts for Nissan Navara 2 weeks ago and I was promised that parts will arrive 2 to 3 days. A week later parts sales man called me to tell me that 1 part was damaged and that he will get it sorted. 2 weeks later many follow up with no feedback he then calls me to tell me that the damaged part has arrived but he didn't notice that the other parts on the order were not delivered. Only after 2 weeks really! The vehicle is a company vehicle and I can't keep paying car hire for their incompetence. Poor poor service. Never buy parts from these people.
