One time we canceled a hotel with free cancelation but the hotel chared us 1100$ anyway. (why the hell did the hotel had our credit card details?!) We contacted booking.com and asked to get a refund, and they said we are right but it takes time... So we contacted Mastercard and said that booking.com won't refund us. Mastercard checked with the hotel and when they didn't get a good enough answer from them they refunded us 1100$. Then booking.com followed up on our earlier request for refund and also didn't get a good enough answer from the hotel so they refunded us 1100$ from their money... Sometime after that we got charged 1100$ by Mastercard... I think that booking.com got a complaint from the hotel that Mastercard reverted the charge and then opened a dispute with Mastercard to get their 1100$ that they refunded us... At least now I know to just go and tell Mastercard every time I get a little resistance from some business who won't rightfully refund me.
