Two Service Accounts, can i reapply my CE code if i delete the new service account?

I made the mistake of creating a new service account with my CE code because after trying to add it to my existing account it said the code was invalid? I know a lo of people are having this same issue and I've already sent in a ticket for it but it seems like no one has gotten it fixed yet. Has anyone tried deleting that second service account and then reapplying the CE code to the original? Would that work or would I just double fuck myself and be left at the mercy of SE shitty customer service for eternity?
