If you pay with a Visa debit card you do have some protection, see the quote below from the BBC website
Visa debit card
A Visa debit card offers significantly better protection for shoppers. Their scheme is called Visa Debit Chargeback and any bank that issues a Visa debit card has to comply with the scheme.
You can claim money back if the goods you buy are damaged, or the product or services are not delivered.
There is no limit on what you can claim. But you have to claim within 120 days of the date you expected the goods to be delivered or the firm going bust.
So this isn't as good as when I use my credit card?
You get better protection if you use your credit card.
The key difference is that when you claim on a credit card under Section 75 of the Consumer Credit Act, the credit card company is legally liable.
But the Visa Debit chargeback scheme is not legally binding, so you don't have any legal redress if you are unhappy.
