Roaming still not working

I have had 4 overseas trips in Europe in the past year. I have requested my roaming to be activated, but it didn't work. Prior to my current trip I contacted Vodacom again and explained the issue and was assured it would work.

Stuck in a difficult situation on my arrival in Germany, again it didn't work. I am able to receive sms's, but unable to send any or make calls or access data. My carrier shows a full bar with "Vodafone.de", I have no other carrier options to select.

How do I get this fixed??
