If you paid by credit card via PayPal, then you have Section 75 credit protection. Which means that you can claim all your money back. This applies for all purchases over £100, including online and foreign purchases.
This is why I always use my credit card for purchases over £100. I only even have to pay £1 on my credit card as long as the total order is £100+ for the protection.
Section 75:
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 shares equal responsibility with 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.
This right is particularly useful if the retailer or trader has gone bust, or it doesn't respond to your letters or phone calls.
Section 75 of the Consumer Credit Act also applies to foreign transactions as well as goods bought online, by telephone or mail order for delivery to the UK from overseas.
