Paintiivo.com review: 'Free' trial that is not cancellable

I booked a free trial at this company and tried to cancel it the next day. The facebook page is unresponsive. There is no response from the company when I tried to contact them and no way to cancel it through their website therefore you are automatically charged 7.99 afterwards. As I booked it with a debit visa I could not just reverse the charge but had to cut and reorder a new card at a massive inconvenience to me. I was very vexxed.
