I did chat with an agent today, Ryan, who was super helpful. He said there was a sync error on the back end. We recreated the error, then he corrected the sync error, then we deleted all the transactions again, signed out, signed back in and they weren't there. However it's only been 2 hours, and I logged in and they're back AGAIN. So I'll be back to dealing with your developers over this issue. 

Those articles you offered are standard help articles for how to operate your software. They do not offer any assistance with troubleshooting. In the absence of knowing how to help, providing completely irrelevant articles is not a good solution. It makes people like me more frustrated with your customer care.
