Bad Service

I have paid my Vodacom account and I have been asked to send proof of payment as the payment is not showing on their system. After million calls everyone is transferring responsibility to unblock my line others saying payment still not showing and others say payment is showing someone has to unlock. I have spend almost 2 days on this simple issue due to back and forwards. The attitude of some consultants is very bad towards customers as they don't even know exactly what they talking about laziness to avoid assisting clients. This is my last contract to have with Vodacom. The system now blocked me to say the will call me back but nothing and I can't access the agents.
