Onedrive wont let me save files

Question

I have been having multiples issues trying to save files from powerpoint to onedrive and managing files and folders in onedrive webapp overall.

• i cant save certain file names.
  • i was trying to save a file and it says it already exists.
  • i go into onedrive and it very clearly does not exist.
  • i browse onedrive in the powerpoint app and it also does not exist.
  • it gave me an option to overwrite the file and i try that and it says upload failed.
  • then when i try saving it again it opens a folder in the name i was trying to save it in - a folder that does not have that name. it opened a folder already within that directory but it somehow shows up named as the file name i was trying to save it as.
  • then it replaces one of the other powerpoint files. it doesnt even share the same name but replaces it anyway so i basically just lost another file.
• i have tried contacting support multiple times from the onedrive website but have received absolutely no response.
• onedrive is incosistent about non sign in share i have a folder shared for non signed in users yet onedrive is making them sign in. on some other devices it doesnt.
• files have been randomly renamed
  • numbers have been appended to my files and folders seemingly out of nowhere
