Full Service History just MIA? I don't think so!

I have bit of a mixed review , It saddens me that I had to come here and mention them. My first off service was great , a gentleman named Khensani called me back while I was doing some search work for cars, super friendly made an appointment with him to have a look at the Midstream branch for some vehicles. I found my perfect little Kia Picanto 2010 model, Which I test drove , he showed me all the necessary info eg: my car has a service book etc.. even took the book out of the car to show my boyfriend , because he wanted to know as well . My first car I have bought myself, I was so proud! My car went in for service still under lockdown regulations and roadworthy had to be done and then I got it back ... BUT this is when all went down the hole. About a week after I had gotten my car back, I had driven to my mom, and something told me to look in my glove-box , as I looked and opened my pouch where all the car's info was in , I notice my car service book wasn't there. Puzzled , I searched my car from top to bottom several times. I can not find anything and I haven't had it cleaned yet , because it was still clean, I asked Khensani if he had the number from the place which they had the service done because I wanted to know if the book wasn't put back by accident by them. The lady there (which was super helpful) looked for me and even send me my car's job card(On WhatsApp) on which it states " service was done with NO book" . Very politely I send Khensani a WhatsApp with the info and asked him if he would please be so kind as to have a look for me there , maybe he put it somewhere in some office while he was busy with another client. All he said is he'll have a look.. one and a half months later , keep in mind I'm messaging him on a very regular basis! some days I go with no response , I also send screenshots to the FI Jacqi ( she was very helpful and sweet) said she'll speak to him and see whats going on , seeing as it's not really her department. Which I understand. Last Saturday I had enough it's been OVER 2 MONTHS!! I went to see Khensani and he called the manager , I explained the whole situation to the manager Steven , He even told me to take down his number which I did and I told him I'm giving him till Monday and i'll send him a message , I however gave him chance until Wednesday sending him a very polite message , with him responding that he'll only be in office tomorrow and then he'll follow up , Yesterday I send him another message asking for any feedback, he reads and ignores . I am beyond gatvoll now. I bought my car with the full service history and I wanted it back that way!!
