If a retailer neglects to inform you of these rights, the cooling-off period is extended to 12 months and 14 days. Consumers who pay with a credit card have added security on their purchases, but only if the items cost more than £100 and less than £30,000. “Shoppers are protected under Section 75 of the Consumer Credit Act, which means the credit card company is 'jointly and severally’ liable with the retailer if something you buy is faulty, not as described, or fails to be delivered,” Ms Rook pointed out.
