High Telkom account charges

Incorrect billing amount on my account. I have a R99 LTE router contract. Some how the debit order did not go off on the debited date and the next payment date I received a statement stating that I owe R600. The following amount of R202 for debit order rejection fees are billed twice that equals to R404 for just one bounced back debit order and who knows are the rest of the amounts charged for. I never agreed for debit order rejection fees of R404 and received a contract. This are day light ******* Telkom, you will loose all your customers because of you poor service!!! This is my first time as telkom customer and my last time. I logged several disputes without any responses... All i received are automated email replies with dispute case numbers. Its been weeks without any replies from Telkom. My account is now R600 due instead of the R99 monthly payment of my contract. If I dont pay this amount due, the account will be in arrears for additional R404 rejection fees +other charges. Then my account will be R1000 plus... Then Telkom will register the arrears amount on my credit bureau profile that will have a negative impact on my profile. Beware of Telkom. Dont open a Telkom account, you will be in debt and off paying charges for the rest of you life, that will include unnecessary lawyers fees aswell. Poor customer service Telkom!!!
