Ridiculous extra R202 subscription that you charging for late payment

I have been having contract with telkom for unlimited data (20Mbs) only for R449. I see on my latest statement there is a charge of R202 extra and description is account subscription once off. I called and to enquire and the consultant said is because of my late payment. My concern is that the R202 is ridiculous. Such a high amount, and he said I am not the only one who complained. I don't know if he was trying to make me feel better but the amount doesn't make sense at all. This is a *******. He further explains that its on the contract and if I want to confirm it I need to go to the store which I app**** for the contract because they don't even e-mail or give me copy of the contract.

Why do you charge such a huge amount when else you still get your monthly subscription. It's litterly almost 50% extra that you charging for late payments.
