Penalty for early deduction

Telkom cant decide to take payments on the same day every month and has cost me just over R200 cause they deducted on the 5th instead of the 8th. Why should i pay the penalty for incompatence? The call centre cant help me and refers me to a Telkom store... really, why do you put a call centre number if they cant assist..... time to look for a new provider or will you sort this and compensate me? I will not leave it here...
