My 10 Years old Yahoo account got closed without notice

Yes, it happened yesterday morning. Woke up to login to yahoo messenger and my password wouldn't work. I then tried to change it online but an error about not being able to do so and to contact customer service appeared.

I have sent an e-mail questioning what is happening and here is what i got:

Thank you for writing to Yahoo! Asia.

Thank you again for contacting Yahoo! Asia.

That is 10 YEARS of e-mails. 10 YEARS of important contacts. 10 YEARS of services linked to that yahoo account.

As an advice, don't link anything important to a free e-mail account, or try using gmail for that. Now i will try everything possible to get at least the contact back.
