Toyota it’s useless they don’t care about their customers

My insurance took my car to Toyota Witbank 3 months ago they always tell me that they don’t have parts and I’m loosing Bussiness now because it’s becoming more than 3 months now and it’s a Bussiness car ..when I talk to Mr Hezekel at Witbank he told me that he cannot speak to me as the brought by insurance even if it’s my car ….and now I’m confused and I’m loosing my business every day…but Toyota it’s useless they don’t care about their customers
