Bad Service

I booked my bakkie for a windscreen replacement 2 September. Upon arrival this morning the personnel don't know that my bakkie are booked and were very unorganized. After they inspected my car , I told them I would drive my car into the workshop myself as they are busy with roadworks infront of the store. I then drive my bakkie to the gate and no one opened, i went back in asking to open the gate when even the guy of the workshop asked this specific guy to open and he just said that I can wait. What pathetic service, I left without my new windscreen. Where are customer service???
