Free Zoom videoconference room

[RASSE]

Hello, 

I have not been using my Zoom account for more than 1 year. 

It seems that the personal free Zoom videoconference room - which I had created more than 2 years ago - exists no longer.

However, all my correspondents had my Zoom contact details.

After how long does Zoom Company delete the free conference rooms?

Can Zoom Company make it reviving?

If it is possible, how may I present a request to that end?

Thanks in advance.
