Data Loss Crisis in Apple iPhone 14 Pro Max Following Support Misdirection

I bought this device Apple iPhone 14 Pro Max about a month before the Series 15 came out, so it's the most recent model until Apple comes out with a new one. That being said, even though I have what should be the best model, the phone has given me a lot of trouble, like crashing and freezing and not letting me share with third-party apps. I put in a complaint with Apple Support (Event ID: 102077881066) to try to get these issues fixed. During a scheduled call, the Apple Support rep suggested that the phone might work better after being reset. We did the reset with the help of a professional, and the customer service rep reassured me that the backup that was made during the process had all of my data, including photos. Because I trusted their advice, I didn't make another backup because I thought that the most recent backup had all of my memories and important photos safe. To my disappointment, I found that a lot of data, mostly my photos, had been lost after the reset. This loss has caused me a lot of emotional pain that can't be fixed. Especially the memories I have with my child. I've contacted Apple Support more than once to explain my situation and ask for help. I've cried over the loss of moments that I can't get back, most of which were firsts with my daughter. How can I live those moments all over again, Apple? I need you to answer and give me a solution. If not, I will have to take legal action. I have audio recordings (Event ID: 102127674838) that show that the Apple Care Senior Consultant, I******, admitted that the first Apple Specialist, E****, had made a mistake. I demand that these voice recordings be looked over, and I beg you to fix what happened. Even though I paid extra for the iCloud+ cloud plan to protect my files, losing all my memories because of a mistake made by someone working for Apple is not acceptable. Please know that I'm ready to do everything that needs to be done and use my legal rights to deal with this.
