some reminds stoped to work, no response from support

I've set up some reminders that was working before, but suddenly stoped to.
I've sent 3 'report a problem' through the buxfer interface, several weeks ago without ANY answer.

I'm a paid member for more than 2 years, and can't even get a 'Hey, we are looking to solve the problem!'. Very disappointing.

Two questions to point:
1) the support for paid member should exist, because it was sold!
2) if a remind doesn't work this cause me a lot of trouble, as I need to be searching where is the gap. As I really hate accountability, you can't imagine how frustrating and annoying it is.
