shocking service even when you want to upgrade

I have tried upgrading my contract telephonically 3 times today was the 4th. Nonhlanla Mbatho interrupted me twice and during my explaining that she is interrupting me. service is shocking. i have an open chat on line and Representative Siphesihle hasn't bothered to call me either. i just want to not have my time wasted and upgrade arranged. i am considering going to another company and retain my number.
