Booking.com

I had a booking with booking.com at the royal hotel. I was not going to be able to make the booking as my child fell ill, I contacted them and they said I need to contact booking.com so I did so, they told me they need to check with the royal hotel. I was told I cannot get a refund but they are willing to change my date. I contacted booking.com on Friday 29 June to ask them if it can be changed to 18 August 2018 I have still not had a response from them. Today (01/07/2018) I have received "no show" emails from both the royal hotel and booking.com I will never use either of these companies I have been ****** by them. If they are so hard up for R700 they can KEEP IT!!! absolutely disgusting service!
