poor customer care

It is with great disappointment that I'm writing this communication. I have a contract with telkom since 2018 and from the onset I gave authority for them to debit my capitec acc the last day of the month. All of a sudden I have been receiving smses confirming I'm in arrears with interest, how so? Furthermore I have noticed that my services have been blocked. Called their customer care only to be taken from pillar to post by their *********** agents who gave me incorrect email addresses for complaints department .Is this how telkom make money from people that they don't debit then claim arrears with interest? it is not the first time they're doing this to me it happened in April or May this year and again now NOOO I had enough.
