Missing data

I recieved several emails from Microsoft that were legit.

I was advised I am 290+ GB over my quota for 5GB

I realize my Clipchamp was saving to my personal OneDrive NOT my business OneDrive (where I have 5TB)

Anyway, I opened a ticket with Microsoft and they confirmed my personal OneDrive has 1GB of data in it -- not 290+

Looks like my data vanished... Can you please contact me and help with resolution?
