How to get your deleted conversatios back?

i shared my accoint whit somoene and she deleated al my previous conversations. asked chat gpt and did my own reserch to get it back. AI said i could’t get it back. then i did my reserch and it said that chatgpt does have acces to your conversations for at least 30 days, so afterwarts i ask if i could personaly ask them my convo back. It sends me to the helpcenter that doesn’t work out for this situation, then it seys i need to contact and they respond whit:"Thank you for your email. Please note: This email address does not offer support.

so what should i do now?
