I really need help recovering my Microsoft account

A couple of months ago, my Minecraft account was stolen and they changed all of the security information on the account including the email for the account. I tried effortlessly to get my account back for months on end but Microsoft support was no help and they ended up locking my account permanently even though I am the rightful owner of the account. All of my Minecraft progress has been lost because of this. Microsoft really needs another way of dealing with these accounts because for them, to just lock me out of my account because I was hacked, is disgraceful. I just wanted my account back and at least my Minecraft account that has things on it that are not even one year old but are a lot, and extremely valuable to me. There has to be a way for me to get the account back because I refuse to sit here and just take the fact that my account has basically been deleted by the team that assured and told me that I would get my account in under 5 business days. I was told that a couple of times even after it had been a week or so. I have everything to prove that the account is mine and I don't know how any one else would get the information that I sent the team as it is deeply personal and should have been enough to verify my ownership, but clearly not. I really need some help in this because Microsoft has basically made me lose all money that I have spent on the account. The fact that I have been told to create a new account and basically spend more money on services because of this is also absolutely disgusting because they are telling me to basically spend more money to get access to what I had already paid before. This is not an exaggeration as I was literally told to make a new account and re-buy what I already had. Even if I create a new account for these things, I can never EVER get back what I had. I cannot log out of the account on my computer that keeps coming up with Microsoft popups because I cannot log in. I cannot just accept the fact that it is gone and Microsoft can at least give some sort of compensation. I mean it's my account so what am I supposed to do if I've lost everything? (everything on Minecraft is gone including all my valuable items). Also I have already tried https://support.xbox.com/el-GR/contact-us, https://account.live.com/acsrand https://support.xbox.com/en-US/forms/recover-your-microsoft-account

NOTE: I will not stop trying to find my right until I get the account back. I apologize if the requests are a lot, or annoying sometimes but this is my way. Thanks for understanding.
