Request for contract to change to pay-as-you-go

I just need to let the Public know and report how bad and unprofessional the service of MTN is.<br> <br> 13 July I upgraded my one phone number, the other contract phone number I requested that they convert it to a Pay-as-you-Go. Ref ***.<br> <br> It is now a month later and after follow up on the 2 July Ref *** it has not been done. I feel this is unacceptable as I am paying now for a service which I cancel. Furthermore 18 months later I can still not retrieve any voice massages new ref nr ***. This is now way to long that I wait for proper service from MTN.
