How can I get my Yahoo account of 10 years un-suspended?

I have been a loyal user for 10 years. Yahoo has taken away access to all my friend's email address, all the notes I made in notebook over the year. My Yahoo email address is on my business cards, stationery and printed catalogs. I cannot answer emails from my customers now. I think there is a reason Yahoo stock has gone from $44 tp $22 this year. They do bad things to customers. Even a rattlesnake warns before it strikes. I emailed customer service 20 times, never got a response back.
