Google Calendar Erroneously Deleting Events Over the last couple of weeks, Google calendar has repeatedly deleted the events I entered. It occurs approximately 12-24 hours after I create the event. 

EDIT: In response to question below, it's deleting events created both on the phone, as well as at calendar.google.com.

Is anyone else experiencing this issue? If so, has anyone had luck fixing it?

Finally, does anyone know how I can contact Google directly about this issue? Their "help" page is a labyrinth.

Devices: Sprint HTC EVO 4G, Android v. 2.3.5
Macbook OSX 10.6.8
I used Spanning, which was perfect. Took care of the whole thing. Why google doesn't have this functionality is beyond me.
