trying to get a copy of my webchat history

Hi I'm trying to get hold of a copy of my webchat history for this year. I am feeling very upset. I feel like I have been extremely messed about. My phone was due for an upgrade so I set my heart on the Samsung s22 ultra. I pre ordered it knowing it was going to be a while. I'm not sure how but the person who ordered the phone upgrade ordered a Samsung s22 plus. I know I didn't ask for this because I had my heart set on the ultra. I did ask for a copy of my webchat but it only gave me half of it. I really would like to have a copy of the webchat history so I can see what I wrote down when asking for the upgrade as I feel like I've accepted a phone I don't even really want and doesn't have the things I wanted. I know that the people who do the webchats can access the history and I know there is an option after for me to ask for a copy and I did that but only half was sent to me. I've been a customer since at least 2016 and I've loved being with id. I've got a second contract out last year and I upgraded that with no issues this year. Please can someone help me and help me to access my history
