No response

Good day, we received a letter from your offices with a final demand of paying an outstanding amount towards one of your clients from whom we did not receive any billing accounts and they admitted was there mistake. We made the payment, emailed proof to Jafta and Daniel asking for a written response that this matter has been solved. To date no reply on any of my e-mails. I have phoned and left messages for someone to phone me back, but this does not happen too. They are quick to send out letters, but can't close the loop.
