Incorrect Information

I had purchased a bus ticked with my Edgars card for 25/02/2015, I then requested to change the booking to 24/02/2015 as there is an urgent matter that needs me to be in Durban on 25/02/2015 in the morning. The gentleman that I spoke to advised me that I could not edit the booking however if I cancel the booking , the funds would be reversed to my Edcon account within 3 to 5 days and then I would be able to rebook however when I called to confirm , that lady told me that I need to have credit to rebook in my Edcon card and then only it will refund however I do not have those funds and I am now stranded with no other plan. I am a regular greyhound user and I am extremely disappointed with the service.
