HELP!!!!!!

Hello All,
I’m a total idiot and hired some guy (jeffsnavelydesign) to do my bands website. WORD OF THE WISE HE IS HORRIBLE AND RIPPED ME OFF BIG TIME!!! TOTAL SCAM ARTIST!!!

Long story short, I paid him all this money $$$$ and am completely unhappy with my website. Currently I am stuck with a wordpress website that I have no clue how to edit. I have read a million forums and im afraid that I cant access the admin settings. I dont know how to edit the costume theme he designed and now i dont know what else to do!

He wont answer my calls, emails or anything. Can someone please help me? I just want to edit simple things like colors, the actual profile pic that seems to be on EVERY page of the website and so on. I have figured out a lot of things thanks to you all on the forums! can someone help me edit this crappy website?

thanks!
jenna
