Poor Service and support from the manager

I send my brother to buy ticket for our sister who was travelling to Mtata from Midrand with two kids. The destination was in correct so I went there to clarify and get the destination correct. He had paid R975. I had send him with the sms with the destination and I am made to believe that he showed the teller what was supposed to be the actual destination. Well my complain is not about the destination mistake but on the events that took place on the day of changing the destination. <br> She told me that the price for the new destination was R915 of which the previous one was R975,She told me she will ask if I could get a refund, Whilst she was looking for supervisor i told her I was not worried about refund (looking athe difference it was going to be R60 - [975-915]).The supervisor came and did the process on the computer whilst I was behind the counter sddenly, she gave me money back which was almost R200 shot. we went to the manger and he said he could not help me because the transaction has already been processed and it was my fault. I explained him the events and begged him to ask the teller to spek side side in English but he refused and did not even look at me. he event threat
