Can't Reach Telkom

Well this entire week I have been trying to get hold of Telkom, initially via the online forms and emails and when getting no response have tried calling them at different times during the day. I have moved to Australia and so phone calls are not cheap for me to South Africa. I noticed firstly that my Telkom account has been suspended instead of being cancelled as requested in December. I have also noticed that I have a credit owing to me and since I am not going to be back in South Africa anytime soon I feel it would be only right for Telkom to credit me what is owed to me. If somebody from Telkom could actually get back to my requests so that I may provide banking details for the credit it would be appreciated. How can a company just not answer any queries for an entire week. This is unacceptable, is nobody manning the phones or checking email enquiries?
