Also the page says that I'll never pay more than £69 with that cap which is obviously incorrect if my next bill is £83.
I've now changed the plan which I would have done earlier if I'd known the cap was set like that. As far as I was aware the limit was the amount of data available on the plan. I didn't know about a cap or that it was that high.

It sounds like you've purchased a contract prior to the introduction of £5.00 capping by default.
Plans purchased before this period had a cap set to the Credit Limit which was determined by the credit check result.
£25.00, £50.00 or £75.00.
In this case, yours was set to £50.00.
This would mean the maximum out of plan spend you could incur is £50.00.
This only applies to out of plan spend. If you've purchased add-ons, or have paper billing or any other charges not related to out of plan usage, this would not go towards the cap. This could explain why the bill is higher than your cap.
I'm guessing from your above message, your line rental is £19.00?
We provide the iD app to track your allowances and usage to help keep ontop of when you're coming close to the allowance limit. This app also allows you to manage caps, enable/disable features and where we provide your monthly bills.
Now that you've lowered the cap, this would take effect for future bills.
