I have the same bad experience as others who tried to book an advertised tee time for the Omni Tucson National Golf Course only to find out that the tee time is no longer available, but they have already charged your card their booking fee. If I go back to the advertised tee times, the available tee time has moved to a later time. I tried booking the later time but after they charged my card for the second time, that tee time is no longer available either. I called their Customer Service and his excuse was that the website has problems and they will refund the charges to my card. No refund received after 3 weeks. Golf18 Network does not even merit a one star. They are scammers.
