Calendar makes me miss meetings!

I’ve missed two important dates now, thanks to absolutely NO notification from Apple Calendar. Do I have to set a different alarm in the Clock?! I’m never using calendar again for anything important…Google Cal going forward. Just did a test and it comes up on my screen, with an audible and I would have been ready to interview! I’m not a lazy or disorganized person yet now I come off that way, thanks iCal!!!!
