Zero Customer service

I am honestly tired of Telkom, like how do you make someone pay late payment charge if you debited my account on time during the day you need to debit. I have never missed any payment but i was told my account was at the Collection department. For what i don't know, because i pay my account every month. I think i need to cancel this contract because this just bad. I would understand if I didn't pay but i pay every month during the 24 via left but i am still, my account goes to the collection department. Worse part is when i got a call from the collection department i called Telkom to inform them. But i was advised that they are not sure why i am being called because my account is up to date.
