A family from Bristol say they feel "violated" after booking a holiday that never existed. Jane Ryan hoped to take the family on a dream break to Cornwall but found they''d booked and paid for nothing. She's not alone - a Facebook group has been set up to warn others of the dangers online and the police are investigating.
Dozens of people have paid for holidays at Perran Sands at Perranporth and Devon Cliffs at Exmouth that never existed - no fault of the parks, but of someone claiming to have a caravan for rent.
Becky Watts from Taunton paid £600 for a group of eight to rent a caravan at Perran Sands.
Jane Ryan from Bristol is one of the lucky ones - she paid £550 for a holiday - but when the keys didn't arrive she started asking the seller questions and eventually got a full refund. She feels betrayed.
Most people saw the deal on this Facebook group. We've made numerous attempts to contact the woman behind it - but haven't managed to. Facebook declined to comment.
Haven - who run the two caravan sites - say they're co-operating fully with police investigations and while they sympathise with the people affected, they won't be offering refunds because they were not involved with bookings which were made privately.
Those affected have now had to change their holiday plans - or been left to make the best of their week off at home.
