Vodacom iMessage activation - rude consultant - no assistance all all.

I have never been so livid in my life after a consultant rudley hung up on me while I was trying to get assistance simply because she did not know how to help or even attempt to try!! after tryign to get through to the call centre all day, all I get is a rude consultant! I have been having issues connecting to my iMessage, for activation - I called Apple and was advised to contact my network provider as it seems that my number has cannot send international messages. I tell the consultant this and she told me Vodacom has no setting to activate this. which is completely contrary to what I have been told and read online.
