how to contact Yahoo small buisness help if you dont have an account?

I have hosted my own website and mail accounts with Yahoo for 3 years, but last week my website went down and a day later my mail account vanished. I checked my bank records and found that no money had been taken by Yahoo for a couple of months, this is probably due to me cancelling my credit card after it was stolen in september. My problem is this... I have received no word from Yahoo about them cancelling my account, so I have no address to contact them, and I can not access Small business help without signing in, and now I have no account to sign in with!
Does anybody have a mail address or telephone number for Yahoo small business so I can get them to set my account back up PLEASE!!!!!

866-562-7219 is the Customer Care number for paying accounts. Since you were paying, you can get help there.

Otherwise go to help.yahoo.com and explain fully in your first post.
