@Harris
Despite sending multiple emails, I haven't gotten any response.
Assuming that you emailed an address and did not use the Contact support form, or that you cannot access the support form when your account is in a suspended state, I have converted your post into a support ticket – you should have received an email confirmation of the ticket being created. Feel free to reply to that email anytime with any additional information re your account/billing/etc.
In case you want to check to see if you can still access the support form on your own, please follow these instructions:
