Has anyone had any luck fixing scheduled notifications & files themselves?

I've now reported our issues 5 times and provided information (screenshots/page source) 5 times to customer care regarding the fact that a) files do not perform per their settings b) members receive an error message when trying to join our group and c) they have removed the option to send automatic messages to people upon pending membership. They've told me the issue was being escalated, they have answered back asking for the same info all over again, and I re-send it. And yet no fix. Has anyone managed to find a solution to the issue of files not going out per scheduled settings? Do I just have to delete all our files? start from scratch? And when i do upload a new file, it does not retain the schedule settings we establish for it. It never appears in our notification are of our control panel. I am so incredibly disappoointed with Yahoo! after 9 years of loyalty to them despite having been taken out to dinner by Big Tent, and invited to have coffee with google reps, we stuck with Yahoo! And this is what we get.
