How did you write into support? if you emailed, that won't work.
You must use the contact form here: https://www.dreamhost.com/support/
Be aware that if the reader of the contact form thinks you are not the correct person, they won't answer the contact form either. This can be tricky because you are asking them to email you at a different address than is on your account.
The moral of the story: when you get your account back up and running, maintain a non-dreamhost free email such as gmail/yahoo on your account specifically so that you can identify yourself to support when your account status is in limbo. After you login to the panel, click "edit profile" in the top right hand corner of the page and add the non-dreamhost email address there.
