Insync Deleting files - no support

Hi,
i ordered three licenses month ago.
Since then I am having the issue that Insync is deleting files.

I am working one my workstation on a google files. In the evening I use my notebook to watch a movie or smth. no work.
(both have insync installed).
Next morning i can not find the files in google. Reason: Insync trashed them.
Luckily i find most of the files in recycler bin.

Another case:
(old Support case, have been going back and forth like 20 times. I asked multiples times if I could just speak with a fellow developer from the team and resolve the issue or at least find my files, but so far no usefull reply only the support beeing evasive)
I take a huge chunk of local files, drop them into an empty shared folder of insync to upload them and sync them with my google drive. Due to space restrictions I had to cut them out instead of making a copy. After one day of uploading the files marked “uploaded” and i unsync the local copy. (not delete them, just unsync with cloud). Next: The files are gone. Literally gone. Not in insync locally, not in google drive. Allegedly i could find them in the HDD recycler bin. But that was sadly not the case. GB of important documents lost forever. You may say, naive from me. Granted. But this should also not happen. The issue is assume: Insync is uploading the folders and creating placeholder folders in g-drive. When it is done it checked if all folders are there. When unsyncing the local files, insync deleted the entire folder tree. But it never actually uploaded them, only file headers and empty folders.

I ask now here if someone of the devs is hearing this. Otherwise I like to return all my licenses as insync is destructive.
