Online travel agency Loveholidays is warning customers that fraudulent callers are posing as Loveholidays staff.
A message on its Facebook page says: “We have been informed that fake callers posing as loveholidays representatives have been targeting our customers and asking them to provide bank details in order to pay a £25 refund processing fee.
“These are not legitimate calls: we will never ask for bank details over the phone or ask you to pay a refund fee.
“If you receive one of these calls, please do not provide your details and report this fraudulent call to the police.”
The post has received more than 2,000 comments from customers.
The message links to the FAQ section on the Loveholidays website, which adds more detail.
It says: “We urge all customers to be vigilant for such activity to ensure that they do not fall victim to such behaviour. If you are uncertain that the person contacting you is from loveholidays, please end the conversation with them and get in touch with loveholidays through our official contact channels on this site.
“Be vigilant for phishing emails. All of our emails are sent from @loveholidays.com.”
A Loveholidays spokesperson said: “We became aware of this scam on social media and from a couple of customers who have advised us that they have received scam calls.
“We have warned customers to be cautious with their personal details on social media as we want to ensure that they don’t fall prey to a call from a scammer.
“We have reported this to Action Fraud and recommend that customers who receive such calls also do so.”
