My account has been hacked, I’ve been dealing with the issue for a month, and I have been completely run in circles. What do I do now?

Somewhere around the end of July my account was hacked. I've had this account for quite awhile and it has a lot of personal information in there including my tax forms, clients, and family, so I considered this as an urgent issue. The hackers made a mess of my account. They changed my recovery email, and my security question is invalid even though I'm sure it wouldn't be anything else. I figured, no biggie, I'll contact support they'll help me. I've dealt with customer service before and did not have a problem getting my email back before. This time was completely different.
For the past month I have been lied to and run in so many circles I'm dizzy with frustration. I've talked to 3 live support members, all of which just dumped me into "Level 2" support. At one point I didn't get a response from Level 2 for three days. At this point it's been a total of three weeks since I first contacted Microsoft Support, so I contact a live agent and spoke with her for at least an hour. During this conversation I was treated like a moron and basically lied to. I was told by this employee that I "was talking to the billing department" and not the actual escalation team, and that she would "link me to the right department". I promptly told her that was not true because why would the billing department email me about my email? After not getting anywhere after an hour I just took her link and submitted another escalation form only to be told that I already had an escalation form open!
During all of this, I just get the same responses.
"Get a recovery code from your phone." Yeah I've done that multiple times and your system tells me there is an error and to check back later.
"Get a password reset from your secondary email address." That would be awesome if my recovery email address hadn't been changed.
"Send in a Recovery Form." The first three I sent in, I didn't even get a reply. I've probably sent in a total of 9 of these forms by now. Tell me, how is it that I can't recover my account if I know my past 5 passwords?
I can't tell you how many times I've heard all these responses and nothing has been done to further help my situation. I just get the same scripts over and over again.

I don't want to talk to a robot that receives a paycheck to send me scripts anymore.
I can honestly say this is the worst support I have ever received. I've supported Microsoft products for many years, but now that I see how I've been treated, I'm not so sure anymore. So what next? Is the next message I see going to be a repeat of what I've been going through for the past month? Has anyone else had this issue?

>I wanted to add that I just submitted a recovery request form. Microsoft is now telling me to just create a new address because I've submitted too many. Am I supposed to let the criminals who did this to my account just have it? Is there any way to shut the account down if that is the case?
