Dealership loses service book in less that 7hours

Took my car in for a service, the front lady is the friendliest person I've ever seen, I was well received. Everything was great, the car was spotless. I had no idea it gets cleaned when you bring it in. The cleaning team did a wonderful job, last saw it that clean when I was getting out of the dealership in 2024. Minus 2 stars because the lady (Ayanda) handling my things lost my service book, she offered a new one without looking for my old one. I told her that I have time she can look for my old one. Later she comes handing me a booklet saying she found it in the pile. I opened it outside just before getting inside my car and realised she **** to me and gave me a new one saying it is my old one thinking that I will not open it there. I told the driver who shuttled me to work to please tell her that I am giving her the rest of the week to look for it. She'll call me when she's found it and I'll collect. She rang my phone once on a Monday. I called her back on a Tuesday and they told me she was busy and asked if she can call me back. Weeks have gone by and she has gone quiet. I want my book back, it holds sentimental value.
