No International Roaming Activated - Shocking Service

<p>I called Vodacom over a week ago to activate my international roaming service (not the first time I have tried). I received SMS's and the consultant told me that the service had been activated on my phone. I travelled to Germany last weekend and when I arrived I saw that my international roaming was never activated. I have tried multiple times this week to activate this service via my online profile, sent an email at the beginning of the week and tried the online chat option. I have never had any response to my email or via the online chat. What is the point of the online chat if there is nobody to chat to....</p> <p> </p> <p>Please could somebody assist me as I really need to use my phone while travelling.</p>
