Auto page management REFUSE to take customer calls

I am battling to get a cell number ported twice now the application has come back to the MTN consultant as denied. I again (for the third time called Altech Autopage call centre where Dorda did not know why the number could not be ported and when i asked to speak to a supervisor she put me to retentions where I spoke to Numsa. She just gave me conflicting information and then wanted me to rather email [Email Removed] because she could not help me. When I insisted on speaking to a real person like supervisor or management as I had been waiting so long to get the number ported she told me \they don't take calls"!! I again asked if she could put me to anyone in management she said no that they do not take calls and I had to send the email. When I asked her to please just let me know what the problem is she promptly put me on hold where after 5 minutes of holding I gave up. - I wonder if this is how they retain customers"
