Recovering deleted references

Hi, I just deleted my entire references with the intention of syncing it back, while syncing it also deleted the online (web) version. Please what do I do? I am absolutely in trauma.

I would approach tech support (fast) if you have no backups.  Maybe they back up their cloud?  

I wrote to the Tech support and there was no response yet…

A support case: CM-190221-2044326 has been opened with the information you provided. You will receive a response to your inquiry shortly. 

I am still waiting (im)patiently…

Maybe a stupid suggestion which you already have checked, but is the references moved to the “Trash” folder or completely deleted? If they still are in the “Trash” you could select all, right click and select “Restore to library”.
