What a disappointing service

I Just made a booking this morning for my sister and few hours later I got an email saying my payment didn't go through. I tried completing my payment with another debit card. Few minutes later, I get emails to say my bookings were cancelled due to non-payment.

I called and was told that I cant use my debit card for this booking as it is of a closer date and would have been possible if I was using EFT. This was never said on the website and they clarely states that they accept credit/ debit cards.

Now my sister cant come home for her grandmother's funeral.

I am so angry right now and cant even control the level of annoyance Im feeling ow.
