Adept Cosmetics® review for CWILL Back in Stock Notify Me!

Now that I have been using the app for over a month, the test email and text doesn't work and I have many customers claiming that they never received a notification. When I emailed them screenshots of the problem, they denied there was a problem and then 2 hours later they said they needed time to research it. I deleted the app and went back to the Back in Stock app which costs more but never stopped working.
