Poor Customer Service

On or around the 14th September 2020 I went to North West Nissan to purchase Tube Assy Oil (***QF). I first called before arriving to the dealership where I was advised that they do not have the part I am looking at stock however they can order same for me and it will take up to 4 days to receive the part. On my arrival at the dealership I did pay for the part an amount of R550. I was promised that the part will be ordered as urgent since the car is not driving. On or around the 18th September 2020, I contacted North West Nissan just to follow up on my ordered part, where I was told that I will be called shortly. Since then till now, I have never received any call or update of my order. I am really upset by the service of that Dealership, my car was been serviced there,but after this I don't think i will take my car for service there. I heard people saying bad things about Nissan but I did not believe, but now I do believe. What I want is the part I ordered within promised time.
