One thing I have not seen mentioned in posts here, particularly in respect of those people who are having difficulty in getting their retailer to agree to an exchange or refund for their set and made the purchase with a credit card, is the joint responsibility CC companies have.
I found this on the Which website:
Under Section 75 of the Consumer Credit Act, the credit card company is jointly and severally liable for any breach of contract or misrepresentation by the company.
This means it is just as responsible as the retailer or trader for the goods or service supplied, allowing you to also put your claim to the credit card company.
You don't have to reach a stalemate with the retailer or trader before you can contact your credit card provider - you can make a claim to both the retailer and credit card provider simultaneously, although you can't recover your losses from both.
This right is particularly useful if the retailer or trader has gone bust, or it doesn't respond to your letters or phone calls.

May be worth calling you CC company if you fall into this category.
