Progress Disappearance or deletion

I am at a point where I am totaly frustrated by a poor response as I have limited time and have suddenly lost all progress made ever since I had joined the platform for learning. I had all sorts ofd positive talk and now, Im just shaken by this experience. I had completed a number of modules, working towards concluding a number of certificates to comence on courses and from courses to degrees. All my progress just suddenly disappeared and its been a week. I'm left to argue with AI and no human intervention. Its frustrating because I had a time frame to work with and to see it slip away like this. This is crazy disaster. Am I the first and only to experience this?. Has this ever happened to anyone else?
