Cannot send emails

I have this problem on and off when using my 3G wifi router from Vodacom. Seems they intermittently change the settings. When phoning MWEB they say it is a Vodacom issue and phoning Vodacom they say no nothing changed on their side. Well it is now 2 days without being able to send emails. I am receiving mail and can acceess the internet, but in outlook my SMTP server are not connecting with any of the past and new suggested settings. I wish these companies can sort their issues and stop passing the buck.<br> <br> If Vodacom cannot resolve the issue then they need to cancel my contract for data.
