How to delete a profile in a FACEIT?

Is it possible to change the steam id to a new one? If the old one is locked.
I have a prime subscription enabled on my facet, but I lost my Steam account. Can they change me to a new Steam ID?
Or will I create a new facet account, but will the prime subscription be thrown there?

Once a game account has been linked to a FACEIT account, the game account cannot be removed.
You cannot transfer your subscription to another FACEIT account. That’s not how it works.
It is your responsibility.
