LinkedIn Never Helps; Why is There No Support Staff?

I am someone who has been using this account very actively for more than 10 years. My account was hacked about 4 weeks ago. There is a vulnerability; I couldn't understand how this happened. There is almost no method I have tried to get my account back. How many times have I submitted my credentials? I didn't get a single return. This has negatively affected my trust in the platform, and the lack of an interlocutor I can reach on this issue is making the process longer and longer. Why can't I get my account back for more than ten years despite the code I received via email?? Password reset shouldn't be this hard! I was thinking of upgrading to premium, it didn't go well. If your account is stolen, there is not even a single contact person who returns to you.
