Crown Currency Exchange has collapsed, leaving travellers out of pocket.
The foreign exchange operator, which provided currency for both business and leisure trips, has had its operations suspended, while administrators from insolvency firm MCR assess the situation.
The administrators of the Cornwall company have warned customers who have already ordered foreign currency for future trips that it is unlikely it will be delivered.
The company has more than 13,000 customers on its books.
