How to delete unused profile?

I have two profiles with my Enterprise plan, one under my work email, one under my personal email (which I mistakenly set up because I didn't realize which plan I was signing into). 

I never use the free account, and I already have a separate photography plan that I pay for, separate from the company account. 

I've looked at all the support documents on how to delete an account, but I don't seem to have that option when I'm logged into the free plan. 

So, three profiles:

Personal photography plan (no changes, personal email)

Enterprise plan (no changes, paid for by my employer, employer email)

Enterprise plan free (I want to delete this one, personal email)

How do I delete it the free one? Do I need to contact my company's administrator?

Thanks.
