Hi Harold,
I am sorry to hear what happened to you. After investigation, we find out we did try to help you out. When you first contacted us to cancel, it was after our working hours and also it was within the 24-hour cancellation policy. The next day when we get back to work, we contact you about changing you to our next shuttle time which works perfectly for you for free, but you refuse our offer.
In your situation, we tried our best to help. The cancellation policy was informed on our booking page before you purchase our ticket, we didn't try to hold money from any client. If you let us know to cancel outside the 24-hour window, we don't need anything but release a full refund to you. If this situation happens again in the future, I would recommend you contact your travel insurance company to claim the loss back. Thanks for respecting our cancellation policy.
