Telkom, a company of *******?

On 10 July I wrote about a problem I have with ******* debiting from Telkom. On 18 July I was contacted by Noleen from Telkom, stating that my 'query' had been handed over to the billing team for assistance. I have not heard anything from Telkom since, and another ******* debit has been deducted from my account. This means another trip to the bank, transaction costs which I have to carry, and more frustration about the inability of Telkom to settle this matter. How difficult is it to find out which of Telkom's accounts is mistakenly linked to my bank account? Or is there something more sinister going on?
