StubHub will do you right if your game was canceled by Covid-19.
I was also concerend that I wouldn't recieve a refund/credit from StubHub. My MLB game was cancelled last month. Let me tell you, StubHub stepped up and granted me a full credit plus 20% on top of that--pretty good. Remember, they are a ticket broker. If you want a cash credit find the person who sold your tickets; or better yet, contact the owner of the team or event. I don't think you'll have much luck when you read the fine print. But if you do business with StubHub frequently, then the credit plus 20% is a great remedy on their part. I am not a paid spokesman--just a guy who recognizes the situation we are in, the business StubHub is in, and best outcome for all concerned parties.
