Online and Call Centre service - Very Poor

Second online application with very bad service. Tried to upgrade my one contract with an online only deal. Got an @mail after my application that says: "It looks like we lost you somewhere during your application." and that a call centre agent will be in touch to complete the process... But after a week, no one called back. I called this morning starting with the number for any assistance, 083 135, shown on the mail, but they gave me another number for online services to call, ***. I have been transfered to agents that transfer me to other agents for 40mins. I wont recommend using any MTN online services - or consider MTN for your upgrades anymore unless you like going into the MTN stores. I have been with them for 17-years now, and it is slowly coming to an end now - me being with them that is...
