Unsuscribe premium accounts with mails thats don't exist anymore

[fefineitor]

I want to unsuscribe 3 zoom premium acccounts that belonged to 3 ex employees from the company i work to and that were paid to run annually. Unfortunatly, the mails of these ex employees, that were related to de zoom accounts, don't exist anymore, so i can't access to the zoom accounts. Does anybody knows how can i unsuscribe these accounts? or where can i write to solve these... I'm from Chile but the way, so there isn't a support phone for my country

Hey, @fefineitor –

See this Zoom Support article for complete info. Sounds like you want to delete these users, so scroll down to the Delete User section.

Basically, deleting the user will free up the license allocated to them. If you have new/additional users, you can assign these freed-up licenses to them.
