Thanks for the advice, I will also say that whatever files I had would not be of much use to anyone on their own and now they're all gone anyway. Sadly no time to see a lawyer before, but if I feel like they're trying to trap me or make me sign something I will say I need to speak with my lawyer.
Thank you for your reply, I will keep that in mind. Sadly I don't have time anymore to go see a lawyer on such short notice, but I will keep in mind to keep it short and stick to the misunderstanding, and when in doubt I will say I need to discuss this with legal council and not sign anything without doing so.
Yeh, I just should've resisted the temptation, or at least be precise about it, but I was worried I was going to lose access
