I cant log in!!!!

I cannot seem to login, I have tried password after password but yet nothing, I even entered the password the wordpress sent to my email when I first made the account, and that didnt work, when I requested a new password, it says something like error!!

this is really pissing me off I need to talk to a WordPress rep ASAP people are posting spam comments on my site and I cant do nothing about it because I CANT LOG IN!!!
