I did the Booking via Booking.com for 30-02 December they deducted R10 188 but I asked to change my dates to 7-9 December they couldn't help me. They took the whole amount for the booking I was told it's non refundable so my question to them was even if I was dead they would have taken my hard earned money like that the painful part is that I went to Cabanas hotel on the 7-9 December hoping they will use the money that was debited on my account I had to pay R11900 again.
