Tenancy deletion hanging at 33%

Summary:

I am trying to progress through Tenancy deletion but it is hanging at 33% for almost 12 hours.

Content (required):

When I initially created my Free Tier account I used personal details, now I want to change everything to business (username, tenancy, contact details, etc) and possibly purchase some resources, so I thought the easiest way to do that would be to delete my account and start afresh. Following the OCI docs I delete all my resources and requested a deletion of my Tenancy. It jumped to 33% and then hung, and this was almost 12 hours ago now. I am unable to contact Support as a Free Tier account so I don't know what to do.
