Disappointed by the Sales Executive - Paul Schreuder

My car went in for a battery replacement and earth cable, I collected it yesterday afternoon on Wednesday, 17 May 2023. On my way home I realised that the service book and manual with my full service history from 2012 till current is missing. Both were inside a black leather cover since I purchased the vehicle as a 1st owner. I opened the cubby hole to put in the invoice and noticed that it's missing. I couldn't go back to Claremont branch as I was already far away. When I got home I called in to inform them, the lady that I spoke to is Nicky, I left my details with her as the guy that assisted me was not available, his name is Paul Schreuder. When I got home, I sent him a mail as well. This morning I called again to follow up as none of them bothered to return my call or rep**** to my email. I was able to be transferred to Paul. I explained what happened and he's insisting that it's inside the cubby hole, the car is still empty as all the valuable items were removed when the car was taken in. He hang up on me, saying I'm arguing as I was explaining to him what happened. I called again, explained to the lady called Taryn. She took my details down. I am so disappointed with the service I'm getting from this branch, keep in mind that it's my first time taking my car there. I usually take it to Kuilsriver branch, the only reason my car was taken to Claremont is that the Kuilsriver branch moved to Brackenfell and that is far away from my place. As Paul brought back my car yesterday from where it was parked, we were standing outside, I told him that I will bring in my car for a service as it's due in July, he took the service book to check for what service is it? Which I think he accidentally forgot to put it back, because I was also in a hurry and avoiding to be stuck in traffic during peak hour hence I didn't realise that he didn't put it back. All I want is my service book, they can keep the black leather cover and the manual but I need the service book ASAP. I'm really disappointed by his attitude
