Charged 75 euro on a security deposit
Had a nice stay at villa Celine in Maillane, France, but due to a glitch in my banking app making it difficult to send a bank transfer direct to the owner for a 500 euro security/damages deposit, the owner sent me a Vrbo payment to use instead. I thought nothing of it and made the payment. 
After the stay the owner refunded the deposit less 75 euro in Vrbo fees.
It turned out that Vrbo see all payments via their links as a payment on the rental and automatically apply fees, all security deposits should go direct for the host to avoid Vrbo fees but this wasn’t explained at the time by the host.
Host went from being friendly to completely unhelpful when I queried it. Spoke to two different Vrbo support agents who said they understood the issue and promised I’d get the rest of my deposit refunded, and not to worry as it had been escalated.
I asked, since it was Vrbo who took the fees why they couldn’t just refund those direct to me, they just repeated that they’d ensure the host would pay it back to me. I assumed they’d refund the host, to allow them to pay it back.
After a week I received an email to say there’s nothing they can do and need to speak to the host. Which they knew I had done already. Complete waste of time.
Vrbo knowing the issue should refund the fees they took, but equally the host shouldn’t have shared the link to pay the deposit that way without advising me it would cost 75 euro, and shouldn’t be passing on their fees to me. why the charge was also 15% is also odd, as looking online their fees for owners are usually much lower.
Very disappointing experience, won’t be using or recommending Vrbo or the host again. Annoyingly I left a good review for the host immediately after the stay, which I can’t now update.
