Telkom

Cancelled a Telkom landline in January 2018. I paid the full account and never used the line again. Now I am blacklisted because Telkom said I have an outstanding account according to the credit report received from Compuscan. The account number and installment amout totally differ from what I have at Telkom. I sent e-mails to Charmaine Dafel , credit management delisting, but she don't reply. Phone Telkom but they don't answer 10210 I got cut off twice. I can't find other e-mails or numbers to contact Telkom to get the matter resolved. It was the same struggle to cancel my landline with Telkom take 3 months to do it. I really want my name cleared, because it is not even my account Telkom got me blacklisted for. Telkom never phone me or e-mail me to inform me about an outstanding account I got with them. What should I do????
