Refusing refund for services not rendered.

I bought a kayak experience for my son in January 2024 for his birthday. Three times in the last year did I book, organise a babysitter for my daughter (since I am a single parent) and drive to Cape Town, just to have our trip cancelled EVERYTIME.

I understand that weather is a factor, but when we eventually asked for a refund after trying three times, so that I can treat my son to a different birthday experience. I was told I can't get a refund. This after I received a cancellation message that morning to offer me a refund.

How is this fair that you cancel on us three times and when my son decides he would rather go for a different birthday experience you refuse to offer us a refund?
