Unprofessional Service

Went to Lewis to ask for a settlement. They gave me a settlement in standerton and i settled. I got a shock of my life when i went to request a profile update. They told me i still owe about R57. Tell me how? Does lewis think i cannot pay R57?? I need an explanation and if its due, then i will go and pay. I need my profile update as a matter of urgency. How? i do not know. I will not be crucified for mistakes of Lewis. i Have been a loyal customer, so treat me like one.
