@servel333 Support can assist with this in the sense that we’ll advise you that you’ll need to delete one of the accounts, which can be done via your account settings page.
I wasn’t able to find an existing feature proposal issue for merging two GitLab.com accounts (or accounts in general), so if you’d like to see this implemented please feel free to submit one. If you do so, you can send me a link to it and I’ll ensure that it’s labeled properly.
