Urgent refund due to system not being updated remain u refunded 6 days later

On the 7th December I booked the mini bus online on our way to the funeral in Limpompo price was good paid with credit card problem is the chosen bus was available only online none on their Springfield branch.Refund not yet back in my account today on the 13th December. You would expect that since it's their system that is not updated re avaliable vehicles, they will be more considerate and refund me on site having driven all the way to their offices already. Needless to say that the money that is being held in the company for 6days was for traveling, had to travel on a limited budget adding unnecessary stress to the family already in distress due to the loss of a loved one. Companies are not run by computers, directors and people in management should be more humane, try and put yourselves in the position of the people you are meant to serve.
