THIS IS NOT FAIR AT ALL

i'm not happy at all after i made an agreement NSFAS this to pay R300.00 now on October i saw that they are deducting R1019.00 on my salary with out telling me .i'm not happy at all.i'm in the lower level in the department ,how i'm going to survive this month only God knows.I fell like this is unfair to me .I did call the call center but they don't help me at all.

i WISH SOMEONE CAN CHECK THIS ,I KNOW I HAVE TO PAY THE MONIE BUY I THIS THEY NEED TO STICK TO THE AGREEMENT I MADE WITH THEM .
