Booked hoover dam tickets. Website malfunctioned. Did not think had taken payment and no email tickets arrived so rebooked. This time the order appeared to process but still no tickets received. Called to rectify, they were extremely unhelpful, told me I had paid twice but wouldn’t refund me, nor would give any information about the tour I’d booked for the next day - no pick up time, no location. So now I’ve lost a load of money and have no tour to show for it. A disgrace of a company. AVOID!!!!
