telkom mobile sales worst callcenter on the planet

i have been trying to call the Telkom mobile sales call centre for the past three days but none of there call centre agents seems to be interested in doing there jobs and answering the phones. I have made more than ten calls over the past three days and i have been kept on hold for more than 20 minutes on each call. i managed to get hold of one of the call centre agent Mandla Shangi from a different department and he could not assist me, I asked to speak to his supervisor / manager of his department and department head Jabu Malete refused to talk my call. he said he will get back to me and so i gave them my contact details, no one has got back to me as yet. it is really ironically that Telkom being a telecommunications company,no one is interested in answering there phones. Telkoms mobile sales department is the worst call centre in the world, this is really sad
