Explaining the process of what to do when facing a scam, the MSE team wrote: "Call the 159 hotline if you've provided card or bank details. This will connect you directly with your bank.

Make sure you find your bank's contact details independently – for example, by calling the phone number on the back of your card or on your bank statement." The next step would be to report the scam via the Action Fraud website or by calling 0300 123 2040, for those in England, Wales or Northern Ireland. ‌ For those in Scotland, you can report scams to Police Scotland on 101, or call Comsueradvice on 080 164 6000, or visit their website. MSE added: "Another option (UK-wide), if it's an online scam, is to report it to the Advertising Standards Authority. Do this in addition to reporting it to Action Fraud or Consumeradvice. "Use Section 75 if you've been scammed when paying for something costing more than £100 on a credit card. If you used a debit card or spent exactly £100 or less on a credit card, you could try to claim your money back under the chargeback scheme instead.

"For more help and support, contact Citizens Advice (England and Wales), Citizens Advice Scotland, or NIdirect (Northern Ireland). Alternatively, call the Financial Conduct Authority's helpline on 0800 111 6768 (UK-wide)."
