Update: cinema destroyed driving licence and are refusing to show evidence

(England) I posted yesterday about how the cinema destroyed my bank card and licence. Well i thought I would provide the update..

After speaking to the DVLA and the police they have both confirmed that the cinema are not allowed to destroy a driving licence and also withhold evidence. Before emailing my complaint I messaged them on X to see if they could help at all.

Funnily enough, they have now changed their policy on the website after speaking with me, to now say they can destroy identification after 48 hours. To which before It just said to contact customer service if you have lost property (I took a screenshot of this page yesterday so I do have evidence of them changing this) I have asked for their legal policies on this and they have refused to provide this and they have refused to provide me with evidence of my documents being destroyed saying

“If it wasn't destroyed it would have been given to you, all items that are destroyed are recorded so there is a paper trail and they are done in a secure room with cameras.”

And when asking for evidence they said:

“As we already explained once destroyed it's then disposed of. We can't help with this matter any further, we've explained that the process and policy is correct. If you wish to make a formal complaint to the police then you can do so, we have explained that this was all correct and the team followed procedure.”

Any further advice on where I stand now - can I continue with a complaint or is there an appropriate body I can report this too.

UPDATE: just received a message on x from the cinema. They have said after investigating, they actually do have the licence. They are now saying they told me in person my licence was sent to the DVLA and I am lying.

They have also edited their messages on X to change what they initially said. Luckily I took screenshots which show the original messages.
