No Service

i have been trying to get a contract from Vodacom for the past 3 weeks now, either there is no answer (due to high call volumes) or their system is always off line, the lady i spoke to first was never at work so i had to re apply for this contract, now everytime they phone me i have to get a one time pin, which only comes through after 30 - 60 minutes then they need to re do it as the one time expires within 1 minute after sending it. now when she phoned me back she said that she cannot help me due to the application being blocked because she already send the one time pin twice, now she will phone me back when my application is no longer blocked.. seriously Vodacom, get a better system or more people to assist as you guys can obviously not handle all the load work. Really dont even want this contract anymore. and worst is this is a SIM Card only contract and they cant even do that.
