Lack of service

I am so frustrated, and find that Vodacom is completely wasting my time. I have an account on the My Vodacom, but when I login I am unable to do anything, including view invoices, transfer data buy data or goods, etc. It is always \frozen". The Customer Care centre is no help at all. I have reported this more than twice. I find myself going from pillar to post to get to the right person to talk to"
