any1 good with contracts?

[-Tigger-]

well.. just when u think ur out of BT's grasp..

when they introduced the up to 8mb connection (we were automatically updated and billing swapped, without permission!..) phoned up today to cancel the BT broadband connection.. now heres the thing, i only found out i was on AOL when i couldnt connect this morning using the BT details, they told me that we "signed" up to a 12 month contract (May 06)..

now heres the question, is it worth paying out the remaining 5 months, or take it up with them that they done things without permission and why the f..k they deactivated our line without confirming it (whats the idea of cutting of the line and expecting the rest of the year to be paid)?
