Huge probelms with Creative Cloud, it crashes twice daily and we lost a very important file.

Having huge problems with Creative Cloud. I have a VIP account, 5 licences. Everybody is experiencing app crashing. As a result I lost a huge document that potentially could have cost the company thousands of pounds. (luckily I had a pdf) the file is completely corrupt now. As a result I am trying to use cloud storage though syncing, im told is yet available to me to locally to do because im told this feature is gven out in 'batches' even though the adobe website says 'As a member, you are entitled to download and use new features as they are released; you get the best tools straightaway'. I have tried calling on the phone and though the person was helpful very little was identified as possible causes. On chat twice and the best advice was to log out and back in again. Please help, having the threat of files becoming corrupt because of daily crashes is completely unnacceptable. What can I do?
