Oh. Sounds like there has been a falling out! I'd try the underhand and sneaky tactic of getting someone else you know to ring up the web design people. Say how nice the site is and other ones are in the portfolio, how fast it is and casually enquire who they do their hosting with...hopefully they'll say.
Then you can then contact the hosting company directly and find out to take control of your site again. Depending on the contract with the web design company you may find you can get the domain back to build a new site but not get hold of the ability to edit the current one.
