faulty app and POP notifications

I made a payment to a service provider and they have not recieved the POP from Nedbank still as I added an email for the POP. When I log into the app to retrieve the POP and send it to myself it retrieves the wrong POP and sends it via email. That is detrimental as the app is now sharing my other personal information to the wrong people. I need the POP asap to secure this service provider so please get your app working!
