O2

Finally sorted via Twitter, I've been blocked for a month but still getting charged 4.99 for travel abroad, no explanation for either but sorted finally. Thanks for all your helpful suggestions.

No data, no SMS, no phone signal at all

Or im sure there seeing a connection or attempts which is what I've been charged for, but I don't have any O2 connection showing at all.

If the chat app actually worked it would not be as much of an issue, or they answered Twitter messages.

There is two main problems here obviously beeing charged is one the other is that non of my two stag verification apps now work. As I have no SMS.
