I rarely post good reviews and never post bad ones, but this goes a long way.
August 21 trip booked (I thought): site is fixed, amount has been debited. Contacted customer service.
Had several contacts, including the question whether it was written off to me. So yes.
Due to a technical malfunction, the booking would not have been recorded (so paid).
August 24th comes the suggestion to rebook: Travel is still available for the same money. (However, this also means paying again of course).
Called anyway after that e-mail: it was still manually recorded.
The same day the message comes that the trip is no longer available (so is suddenly sold out?) And people ask for my account number for crediting (you can also refund on credit card, so this was another separate question).
On August 25, my account number was passed on, the receipt was confirmed and the order was sent to the credit department. (They say).

Took a long time, got back in touch. 'We will refund it within 10 working days, we probably cannot speed it up'.
Well after those ten working days, another email was sent (quite bluntly) and received no response.

In summary: it is now September 19th. We are 18 working days and 25 normal days further since the promise of crediting a (quite considerable) sum of money that was never paid for by a product or service, in fact: 'my' product / service simply never existed.
Price Free holds a sum of money that should never have come into their possession, nor should they have remained. In addition, my money has not been available to me for almost a month.
Very disappointing is putting it mildly.
The last word has not yet been said on this.

Update 20-9: yesterday also put the problem on complaint.nl (where price free has joined itself). Prijsvrij has already made the effort within 24 hours to 'not deal with the complaint'. Turning down complaints can apparently be much faster than doing chargebacks. Perhaps redistribute tasks? We go on...
