Facebook Suspended My Account Due to an Instagram Account That Doesn't Belong to Me

Hello, my name is N*** Ö***. My Facebook account was recently suspended due to a connection with the Instagram account "vohung*****," which does not belong to me. I have only ever had two Instagram accounts linked to my Facebook: "n****" and "nit****." I have no idea why my account was associated with this third-party account, and it seems to be a mistake. I’ve been using the same Facebook account for 18 years, and it’s an important platform for me. Therefore, I’m requesting that the suspension be lifted and my account restored. This issue is causing unnecessary trouble, and I hope it can be resolved quickly. I’ve always followed the rules, and this seems to be a misunderstanding.
