I cancelled my reservation at this hotel, and they still haven t refunded my credit card after a week. I noticed this morning that they charged another $50 to my card today! Good luck trying to reach anyone who can help me-calling their front desk sends me straight to a call centre in god knows where, and whenever I ve reach the centre they say they can t even see the charges on their end. Now I have to open a dispute with MasterCard, because apparently refunding a customer is too difficult. And changing their card fraudulently a week later is the cherry on top! Amazing work guys, truly. Hope you re enjoying my $220.
