Telkom pathetic service

I recently had 3 contracts with telkom. i cancelled 1 because of the bad service and unfortunately I still receive bad service from them. after being with telkom for over 4 years now, I recently find out that they have been charging me penalty fees for late payments. They have been suspending my accounts after debiting my account every month. i called the agent at telkom for a refund on my penalty fees because it isn't my fault that payments are late as my debit order is set and they continue to debit on the correct date but the agent cant explain why there's penalty fees for late payments. its basically phoning the municipality for help, you get no nowhere. i do plan on cancelling my existing contracts with telkom. Pathetic service !!! They basically robbing me and i just have to accept it. they dont debit whats on the invoice. they take whatever they want from your account, disgusting and ridiculous.
