Is there a way to get a recording back

[CK15]

Hi,

I was on an very important and informative call that I pressed to record so I a can rewatch it again later to absorb all the info.  I didn't sign into my account and when the call finished it was finalising the recording,  when I can back to the screen all that had gone and the zoom sign was just there instead.  I didn't get a chance to save the recording anywhere which is what I assumed would happen.  Is there a way I can get this recording now at all?  I tried calling the support line but it just keeps saying they don't recognise my account.
