The customer service is very poor and not helpful

On the 1st of March I was trying to purchase my 35 days pass from Hatfield to Centurion and the agent (ID 2235) shift ID 10316 mistakenly loaded R2237 to Sandton instead of the correct amount of R1045 to Centurion. I checked my slip then I saw the mistake and quickly went back to report the issue,the agent then told me that since the transaction was EFT the amount will be reversed immediately in my account.I went to work, later went to the station to ask why the money was not reflecting , the agent that had made the mistake was gone and Thulani/Kolani who was the supervisor on duty made me fill in a refund form which is the necessarily procedure for a refund ,and then spoke to another supervisor who issued me a letter to use for access. <br> <br> I used the letter from Wednesday till Friday with no problem . On Monday the money was still not paid and I tried to present the letter to Yuta who turned me away and suggested I buy a new card while they caused me the inconvience ,she then told me I must stop shouting as she will call security to throw me out ,I am really dissapointed in Gautrain customer service,I couldn't even buy my toiletries and food. I was compromised by someone's mistake
