The payment is just the initial deposit you did, no more.
The problem has occurred as your account has been hacked.
First, it is very important to change your password. Do this asap and make it as complex as possible.
Then click on my link below to request that your conntats are restored to your account (as the hackers delete these)http://help.yahoo.com/l/us/yahoo/contacts/restore/ab_restore.html
Allow 24 hours for the contacts to be restored.
For the emails, please use this form to request that the emails are returned to your account.http://help.yahoo.com/l/us/yahoo/mail/ymail/restore.html
Also allow for 24 hours for the emails to be returned.
Please do this asap to ensure the best chance of recovery.
The reason this happened is they obtained your password, either by guessing (they us a program for this) or you gave it out via an email (never ever email your password).
As long as you make the password XXXXX (use small letters, big letters and numbers) you will avoid this occuring again.
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
