Eldo coaches refuse to give us our refund for the retirning trip and we are not willing to use them in future

We booked with Eldo coaches return tickets from Johannesburg to Cape Town 26 April 2018 13:00 to Cape Town 29 April 2018 13:00/30 April 2018. Which we had to board outside Park Station. We got to Cape Town ,we were told it wasn’t save to drop us off where we should have, we were dropped off at Bellville instead of Cape Town Station. We had to find our way out by asking around. We then asked driver if the busses will be available and we were told that anything can happen. So we decided to have plan b, after we heard about a bus that was burned down, we did not want to risk by putting our lives in danger too. So we had to make other plans of returning to Johannesburg. We tried to get tickets refunded at Checkers and we were told we should contact Eldo Coaches as the money is already by Eldo coaches. I am sending the email as we couldn’t get help from calling your offices on Sunday for further assistance and for clarity about the busses. Here please see Ticket numbers below. Where should we go for the refund? You may call me on ********** 185.
