Private telegram group chats

I was hacked last year from my icloud I thught it didnt di anything so i just changed my password Now after 1 year my ex told me that my private videos with him including my profile on facebook and my private pictures of me are being sold on telegram and is now through twitter We had multiple reports on twitter post and even with the username that posted it without our consent But twitter replied that it didnt go against their policy , we tried to pay IT people to take it down but no chance Were now about to file to NBI cybercrime to see what we can do Any advice who has been in this situation? Because i havent slept for a week and we dont know what to do anymoee
