You're right. I had almost 2000 transactions we had to delete because of the late fee glitch. Then when they came out with their "fix", it credited all the customers with a late fee after we fixed all the invoices. Creating another 1000 or so that had to be taken off. We have stayed on hold multiple times, just to be hung up on after sitting there an hour. On top of that, payments that are linked to invoices magically become unlinked going months back after an update they did a few months ago. It's a nightmare.
