Pay-as-you-go and Voicemail

I just need to let the Public know and report how bad and unprofessional the Service of MTN is.<br> 13 June I upgraded my one phone number, then the other contract number I requested that they convert it to a pay-as-you-go. Ref ***.<br> It is now a month later and after a follow up on the 2 of July Ref *** is has not been done. I feel this is unacceptable as I am paying for a service which is not rendered. Furthermore 18 months later I can still not retrieve any Voice Messages Ref ***. Every time you phone to enquire the operator said it will be fix within 48 hours, its now 18 months later.
