telkom business and stores - no response

As an existing Telkom client I went to 2 stores to apply for a Telkom diginet line and both advised me to contact the call centre 10217 for Telkom business. I have been calling Telkom daily for 1-2 hours for over 2 weeks holding on the line and no answer. I finally dialled another Telkom number and a guy said he will email the call centre manager and yet still no reply.
