BAD SERVICES FROM VODACOM

I upgrade my phone about 3 weeks ago, since then my vodamail email didn't work. I had phone Vodacom about 30 times to assist me. At first I was inform that during my upgrade they didn't add my vodamail email to my new package, but will assist me to add it again. Since today I can not used my email. I am a business men and don't have excess to my mail for the last 3 weeks. Every day there is new promises and new password is send en given to me, to excess my mail. Nothing of that is working, then a sistem error was blamed. Can a sistem error last 3 weeks. I'm a Vodacom customer for 15 years now, and very dissapointed.
