Action Society: impossible to cancel donation

Be careful about becoming a donor to this organisation as it seems almost impossible to cancel a donation. there are no email addresses on their site, only a contact form to donate to them. In other words, once they have you in their grip they do not let you go. The payment gateway is unable to assist. if I even had second thoughts about continuing to donate to this organisation, finding that they made no provision for cancellation would really put me off
