If I pay for goods with my credit card and the product is defective, is the credit card card company in any way liable?

In situations like this the customer should first of all complain to the retailer involved. If the dispute is not resolved, however, and the customer has paid between 100 and 30,000 for the product using a credit card, then Section 75 of the Consumer Credit Act applies. This means that the card company has equal liability and you can get your money back from them. This would also apply in a situation where the company involved goes bankrupt and no goods are received.
