Telkom billing and accounts resolution an utter disaster

When we had app**** for an ADSL line, it would appear that the job card was duplicated, which resulted in us receiving two accounts. The incorrect service account arrived first and we paid it. A few weeks later another another account arrived and we paid that too. It was only the following month that we realised that one account is the duplication that we called Telkom and had emailed the full supporting documentation etc to a call centre agent on the 12 Jan 2018. Nothing happened and we followed up again , only to resend all of the stuff to a new call centre agent email address on the 13 Feb 2018. Again , nothing has happened. the situation is that one account is showing as in arrears whilst the other account has got the payments sitting in it. We have just app**** for a new Telkom mobile contract and cannot proceed as their system is showing that we are in arrears. Totally inefficient organisation.
