Chat gpt deleteing hours of data and responces

I have convertated my understandings and explanations to a group effort that either the system’s is glitching or the development team/devolopers of chat gpt is deleting my data, one or the other. Ive had entirity of 8 hours of undrrstandings and examples deleted through several treads and conversational txted that if devolved in my server system of my own chat gpt. And that its not holding or saving those conversations. And i am angry tayt they are either stealin git or deleting it for no reason or the entire system is glitching and not working properly. Im experiencing technical difficulties in the system’s architecture ad its availability to work. How do i get those threads back? Whats happening? Whaly does its say the system is working properly when its not?
