Ashley Gibbins: hero to us all:

When taxi driver Ashley Gibbins called the helpline of NTL hoping to have broadband installed, he was told that all its operators were busy right now, but if he cared to hold the line his call would be dealt with as soon as possible. So Mr Gibbins held. And held. Then held some more. Eventually, after an hour, Mr Gibbins decided he had had enough. He put the phone down and decided to wreak his revenge.

By chance, Mr Gibbins discovered he could alter NTL's recorded message, and after he'd tinkered with it people seeking help were met with something altogether more blunt.

"Hello, you are through to NTL customer services," they were told. "We don't give a fuck about you, basically, and we are not going to handle any of your complaints. Just fuck off and leave us alone. Get a life."

...The magistrates decided Mr Cleveland's rant was merely offensive, and did not make the "grossly offensive" standard required for prosecution.
