Debtbusters Do Not Care

I received a notification from ABSA bank that payment has not been made on my behalf by Debtbusters, yet my account is successfully debited every month. I've been emailing Gary Light, and he doesn't respond. Seems like you can email them until you're blue in the face, but they simply don't care about you once they have you on board as a client. I've also been using the whatsapp chat option, and my messages don't get read. I've been trying to call the consultant that took me on as a client and my calls were unanswered and he didn't even try to call back. The customer care line goes to voice-mail. I'm at my wits end, as ABSA is threatening to terminate.
