We do have some issues with the way the sales department set up the account, there's an option in the order for "broadband bundles offer" which can set it to free for 60 days. but I have had a lot of customers coming to me and I've had to give them a manual credit
But yes Im affraid that once the 2 months are up, your in a legally binding contract for the 12 month period. But there are cases where people have tried to cancel but havent been able to due to problems getting in contact, or the trial date ended on the weekend etc.
