Standard Bank Student Loans killing me

Hey guys<br> <br> i took out a student loan at the end of 2012 to study at 2013. At the beginning of this year i started working and wanted to start paying back my student loan. I went into the bank and the guy that helped me said that the calculated plan would be me paying back R2000 a month. My base salary being R5623 i cant afford to pay R2000 and i told the guy that i cant afford to pay that much. He told me that i can change it after i accepted the amount. Being very sinister about this i decided to go along as he said i can change it. I was told to go and get a bank statement and my payslip and then come back so we can change it. I came back the next day as they where about to close and to my surprise he could not change it on site he had to call the loaning department. Calling them resulted in them telling me to sent a email to [Email Removed] I tried sending a few emails to this email address and keep getting a address does not exists back to me. I went into the branch and logged a query***) and again telling me to send a email after not hearing anything from them for a month. I tried sending the email again to that address with the same results.
