Struggle with simple request

I phoned MTN to change this from contract to prepaid. I was advised that it was done.<br> It was not done. Same contract debit order was deducted.<br> <br> I went to MTN in Northern Cape Mall in Kimberley and was advised by Charina Ridgard that system needed to process request was not available but gave me her e-mail address to follow up progress. She said she would change once the system is online.<br> <br> I have sent her 2 e-mails regarding this query, which seems to be ignored.<br> <br> Can anyone please help me to migrate this number to prepaid??<br>
