Calling Autopage is a dead end..

Hi, I have been trying since 19 March 2015 to get hold of somebody at the Customer Care call center of Altech Autopage. Once you have gone through all the voice prompts, the line goes dead. I am constantly getting sms'es to say that my account is in arrears and immediate payment is required, etc. but there is absolutely no way for me to rectify this. When the East Rand Mall branch eventually answer their phone, they tell you that you have to call their call center. So now, I am sitting with a situation that my line may be suspended for an account that is NOT overdue or in arrears. Please help !!
