AVOID... they won't refund your money if your booking gets cancelled
Cutting the long story short, the booking I made through OD got cancelled by the owner the next day. This resulted in a saga of trying to get my deposit money back which lasted several months. After numerous assurances that I will see the money on my account soon I finally received an official reply via email that I will need to request the refund through my credit card issuer!!!!
When speaking to my bank, they have never heard of such practise when clearly the cancellation wasn't my fault and the refund from OD should have been straightforward. However they did agree to raise a chargeback after I supplied them with all the evidence. The bank then applied a credit to my account from their own money while waiting for a reply from OD.
OD rely on people not pursuing their claims as it is completely ridiculous having to contact your bank for a refund when OD are the ones who took the money in the first place. The banks should seek to withdraw the card paying facility from these scammers.
