Naved Q.

I bought Diamond Club tickets to surprise my wife. I have bought from ScoreBig before wirh no issues. When I purchased theae seats, I receives notification an hour later the seller decided to cancel my transaction for an unknown reason. I feel the seller should be in contract when selling the tickets. The seller should I either have to sell the tickets once sold or at least have a cancellation fee for the inconvenience. I mean I, the buyer, has to pay a ridiculous service fee when I buy the tickets. The seller should also be invested somehow.
