Helkom does it again!!

I app**** for a home ADSL service from Telkom. The line could not be installed or activated because no lines were available. I have however been billed since May 2018; and in spite of numerous calls to 10210 the matter has remained unresolved. I have been receiving weekly text messages threatening that I will be blacklisted by the credit bureaus for non-payment. I have now been informed by Transunion that my profile reflects adverse information due to the fact that I have not paid the outstanding amount of R321!!! I am fed up with the empty promises that the matter will be escalated and resolved...the adverse listing will now reflect on Transunion for 36 months!! Helkom par excellence!!
