The firm responded by discontinuing the relationship with highstreetmax.com and saying, 'Once our customers leave our site they are given an option to sign-up for a third-party cash back programme. When they sign up within the terms and conditions it is made clear that further payments will be taken. However we have had some feedback from customers who have inadvertently signed up. On this basis we feel that it is the right thing to do to take this off our site.'
