What to do if someone schedules a date but doesn’t follow through?

So 2 days before Valentine’s Day someone you’re dating schedules a date for that following Monday but that Wednesday after they said they were looking for showtimes & locations and asked what was near the both of us you then respond back telling them but no response… You didn’t hear from them every since then… so you waited on Monday just to see if they would communicate why they haven’t responded but nothing… So you give it another day & there was nothing… You eventually block them until Friday… Was i wrong for blocking them? I feel like maybe they went out on Valentine’s Day but tried to use scheduling a date with me on Monday just in case it was no plans for them… Maybe they reached out to me while being blocked but there’s still no excuse to no communication at all when we literally just talked on the phone that Wednesday & texted… I should definitely move on though right?
