not your bad Jonathan, Virgins bad,
I cant have reached that limit, its just impossible, I am going to run DUmeter for a while (as I have done in the past) and check usage so I can check up on any throttles and catch the bug bang to rights if it happens again.
What I really object to is they say this is to stop criminal activity, this means they are criminalising me for legitimate usage and that really annoys me.
