This is not true
While credit card purchases are protected under Section 75 of the Consumer Credit Act, debit card purchases don't qualify for this protection simply because they don't form part of a credit agreement.
However, most debit card providers are starting to offer a form of protection when you make purchases using your card.
You have some protection for purchases made using Visa, Visa Electron,
MasterCard and Maestro debit cards, through something called Chargeback. (There is a similar purchase protection scheme in place for Amex charge cards.)
The scheme makes it possible for you to claim a refund if a purchase made using your debit card is unsatisfactory, if you are billed multiple times, if you don't receive goods you've paid for, or if your card is used fraudulently.
You can claim a refund for any amount of money so it can also be invoked if you have problems with a credit card purchase over £30,000 or under £100 in value.
Remember that any protection offered isn't a legal obligation (like Section 75 for credit cards) but an in-house rule: this means that the exact rules for chargeback schemes vary by card provider, so you should make sure you are aware of your debit card's chargeback rules.
If you want to make a claim, you'll have to contact the bank who provided you with the card within 120 days of when your goods should have been delivered. If the goods are faulty or your card was used fraudulently, contact your bank within 120 days of when you are first made aware of this.
Ask them to initiate the Chargeback process and a dispute will be opened by your bank, who will investigate the matter and refund your money when this is settled.
If your Chargeback claim fails, you can take it to the
Financial Ombudsman Service within six months of being notified.
I would normally agree with this but with a credit card your purchases are protected.... if you book flights on a credit card and the airline goes tits-up you can get your money back. Pay on a debit card and that's you several hundreds out of pocket.
If you use them responsibly and pay the balance on time you can use them to your advantage.
