bunq Hi Bunq, thats why I was surprised to be refused a Sixt car rental at pick up last week at Eindhoven Airport as they dont accept Bunq Mastercard. On top of that they do not want to refund the full prepayment made with this card a week earlier and refer to their terms and conditions and as such my inability to show a proper credit card….so its defenitely not solved and feels like outright theft. Paid full amount, refused to rent the vehicle!!
