Sync to Google Calendar not working & i can't renew my credit card

The two issues are not related but are annoyng a lot.

The most critical bug:

Complete a task in WP don't make any change to GCalendar.

I tried to reset the sync status (both pull & push are selected): no way !

Only way to sync is to delete tasks manually on GCalendar....

The sync of new tasks works flawlessy.

Another issue: when i create a quick task directly into WP schedule calendar i can't put duration and time schedule. So when is saved the task is immediately transferred to GoogleCalendar as a "day task" (without time start/end); if i change task start and duration in WP, it will not be updated in G Calendar remaining a "day task" (without time start/end).

Second bug:

I need to renew my credit card details but i can't fill the credit card number: simply the field don't accept any data!!!! (it means that you don't want to be payed?)

Few thoughts about that:

From my point of view WP has now too many annoyng bugs, much more than i expected.

Stupid bugs that i have'nt time to notify, beacuse i bought this software to manage in a more efficient way my time and my work.

Spending your time to test the software that is made for better use your time is a NONSENSE!

WP is now a problematic app that i will continue to use, because i need it but also because i hope that you can solve all the problems and bugs in a reasonable time.
