it's a con - the salesman will tell you it's a free trial (which is a genuine offer) but actually sign you up for an instant deal, they do this as it earns them more commission. loads of people at college have been done by the same lads in town. you should be able to cancel easily online.

I'm sorry to hear about your dealings with LOVEFiLM - I have a similar experience of the company. My details were used to set-up multiple accounts at lovefilm (persumambly by the guy who signed me up in a shopping centre) LOVEFiLM won't close the accounts down as I'm not the account holder and continue to take paments despite the fact that I have cancelled my bank card. the company are not great when it comes to problems and hide behind their Terms and Conditions. my advice - never give your bank details to a man in a shopping centre and stay well clear of LOVEFiLM.
