Blog is trashed!

Hello,
I would be glad to note my version, but because my blog is trashed, I am unable to access the dashboard or anything else, for that matter, that makes sense.
If I access my blog by typing in the URL, it is correct. If I try to access the dashboard, most of my pages are missing and nothing is the same since the last time I accessed it. There is only one page left out of about a dozen or so. This is combination of comments, pages, etc.
It is a work in progress; since I have other time constraints, it is difficult for me to “stay on it.” It has been since the beginning of June.
I noticed that there is another user that has a very similar name to his blog as I do, but I have had mine for a very, very long time…long before anyone else used the name. (Actually, I am kind of bothered by even allowing another name that is so close to mine.) As a matter of fact, I pay for the domain name to prove my blog name is original. Last time I was in the dashboard, I noticed the issue and had to alter my name a bit, to keep it unique. The only thing I can guess is that somehow WordPress allowed another user into my page by cross-linking data. Without knowing for sure exactly why this happened, that’s my best guess.
Since I am unable to find a contact directly with WordPress, does anyone here have any suggestions as to what I can do to get this fixed?? I am so frustrated, I’m about ready to chuck the whole idea.

Thanks,
Jake
