Only a partial refund for their mistake!

Very Very poor service. I booked and paid for my ticket online. The payment went through and I received my Booking Confirmation. There is a 10% discount for online bookings. I paid R477 for this ticket. When I arrived for the ride they couldn't find my booking. Even after I had supp**** all the details and confirmations. They asked me to make a payment for the ticket R530, no problem, people do take chances, and they will refund me once my payment was allocated. Then after 6 days, I had to follow up to determine whether they were able to find my payment, which they did. They made the payment to my account, and I even reminded them to do the R530, but they refuse.

The R53 is not even the problem here, but the attitude of the people, not once did they apologize, I honestly did nothing wrong with regards to booking online and making the payments, but I get treated unfairly.
