Still unable to view my bill. Not paying it until I can since I have just changed plans and my bill has definitely changed. If Vodafone tries to ping me the $17+ for late payment I will refer them to this thread and point out at least someone at Vodafone was aware of the issue and it is still as yet unfixed.
You agreed to the terms of paying your bill or facing the late payment fee and/or disconnection or debt collection when you signed up. Under your obligations of being an adult just pay it. I would normally say the bill has also been emailed to you but I understand it hasn't for some people (like myself) but I also know you can get your bill via My Vodafone on their website too.
The app being broken and their email not working correctly isn't an excuse to not fulfill your obligations to them. You're still getting the product you signed up for.
