Lost recording

I hosted a webinar today that's divided into 4 parts. I recorded the webinar, paused the recording during a break, and continued with the recording after the break. I ended the recording after the first 2 parts so the file would not be too big. I repeated the same process for the next part of the webinar. 

Now, I can only find the first part of the recording; the rest is gone. I normally do this for the webinar, and there have never been any problems before. I tried contacting Zoom support, but all they said was there were no active accounts under my email address when clearly I was logged in throughout my whole meeting.  

Can anyone please help ? 😞
