Microsoft rewards sweepstakes are feeling like a scam

I've entered sweepstakes that haven't picked winners. CXO, doom eternal one x sweepstakes, and etc. Starting to feel like a scam and hesitant to use points on. If you don't pick a winner then we should get points back. I get covid might keep some of the
sweepstakes from happening but to just pocket the points seems dirty. I spent alot on the CXO sweepstakes for it to get swept under the rug seems borderline scandal.
