"Stood up"

tonight I made , my 3rd or 4th attempt to attend a particular community event.

The first time I was told that the don't know why I would show up Tues at 6, because the event is at tues. 4:45.

The next time I showed up Tuesday at 4:45 and was told that they changed it to Monday.  (The paper confirms the new night, Monday)

So, I showed up tonight Monday night at 4:45 and was told that it was cancelled, and to come on tues. night.

Maybe it's time to give it up.
