No Vodacom emails for 4 days

I'm going onto the 5th day with no emails! I depend highly on my emails for work and my own personal use. I've been unable to send and receive emails since Friday and am awaiting very important personal info too...<br> I've contacted Vodacom 5 times and they just say my matter has been escalated... No technical advice...<br> Please Vodacom, I urgently need my emails....
