Many devices now have in built data monitors that can go some to help explain what's used what.
Vodafone can only state how much has been used but not what on.
Best practice is to self monitor using the myvodafone applications and account caps and bars.
That and some devices have in built bars that can be set.
Vodafone have been known to send communication to highlight usage but this cannot be relied upon I'm afraid.
Some devices can and will switch from wifi to mobile data if speeds or connections dips although u appreciate what your saying about wifi assist.
A good piece of advice is to go into the devices settings and turn Off Mobile Data when its not needed so theirs no accidental usage.
If your phone has been cut off then it's also a good idea to check your credit file to see if anything negative has been applied there.
I appreciate your not wanting to pay for usage you firmly believe you haven't used.
As you've exhausted customer services the Vodafone Social Media Teams here maybe able to clarify and assist further but if their systems are showing usage then I would think they'll want payment for this usage.
I wish you all the best with this situation..
Vodafone have a complaint process and a timeframe they give a resolution or answer.
Arbitration is considered after that timeframe and or if Vodafone give you a Deadlock Letter which is their statement that they are unable to help further.
