Poor service from manager at Toyota Hatfield

I took my Hilux GD6 2018 model in for a service on the 26th of October. Whenever it goes in for a service under service plan or not, I supply my own part, because I will for example put in the best and most expensive oil in that I can find. When I received my bakkie I drove off till someone stopped me. So there was oil running out from the tail gate. I found a box with all the empty gearbox oil cans that they used, upside down but in the one there should've been 300ml left. My hole carpet and the back of the bakkie was flooded with the oil. Someone from Toyota phoned me and ask how my experience was and told them it was terrible. They replaced my front brakes and it is screaming. Then the manager phoned me back and told me it is cheap brakes that I used. He didn't even know the brand. He said he will sent me a whatsapp on the 30th of October so that I can sent him a photo of the brakes and he said he will make contact again beginning of the following week to come fetch the bakkie to clean it, also to see what went wrong with the brakes. Never heard again from the manager. Poor after service
