Possible Security Breach – Fever: local events & tickets Review

We purchased tickets to an event for on a Sunday evening, when we went into the fever app to confirm the address, our tickets had been changed to Saturday afternoon. To their credit, they did refund our tickets however they offered no explanation as to why my tickets were changed. The event was then marked cancelled in their app, however we had friends in attendance on Saturday so we know it was held, and the event is still listed on the hosts site for Sunday evening, but it is sold out. The whole transaction is highly suspect; did we really ever have tickets in the first place?
