ATCB doesn't communicate

The ATCB needs to get their shit together. Back in July, I missed the deadline to renew my certification by one day, which is my own fault. I emailed the appeals department and never heard back. So I started to reapply and I need a letter of endorsement. I have had my application completed since August and my supervisor says she has uploaded the letter multiple times, but it shows as not being there. I've tried contacting the board and they never respond. There's no number to call and they don't answer their emails. This isn't the first time I've had issues communicating with the board either. I'm just fed up with this board that is so dysfunctional. Anyone else experience this?
