When you visit your client area and select your license, if you click on support it says there if you have a non-technical accounts query, you can use the contact form. That said, I am not seeing any tickets under the email associated with your license since last year. Have you perhaps submitted under another email? If so, could you please PM me that email so I can take a look to see what happened there?
That said, if you are having problems with contact at any point, you can always post up here to state you are trying to get in contact on an accounts question and cannot. We can then create a ticket on your behalf.
