How can I delete an old url

[spud]

I recently canceled a subscription with a company that listed what I "want to buy". When my website is googled, not only does my website come up but so does my "want to buy" showing their url. I contacted them and they said I would need to contact all the search engines myself and have them delete these links.

But google states "Each site on the Web is controlled by its own webmaster. If you find a page in Google's search results that you'd like to see changed, your best bet is to contact the webmaster and ask him or her to make a change."

Please help I'm stuck.
I contacted them and here is the correspondence:




Hi,
I recently canceled my subscription but I still find a link on google. If you google --- you will see the link in number 2 position on the page. Would you please delete this link from the web. Below is the link as seen on the web

Thank you for replying.

We provide value added service to our members, in form of search engine optimization but if you find it annoying according to your privacy needs then you can get rid of this facility by removing your offering from your account or changing keywords.

But in your case, as your account has already been removed, your optimization has been canceled but different search engines (i.e. Google, Yahoo and AOL) keep a database of all the entries it receives within a time period.

You can contact Customer Support of these Search engines & let them know your problem.

It would be my pleasure if you let me know either its works this way or not.


Can Google please point me in the right direction to resolve this ??

Many thanks
