Poor Service / No service

Upgraded my contract online on Monday(06/04/16) got a reference to say they will phone me back in 24 hours. What a laugh. After numerous attempts contacting Vodacom on ***4 as per sms and the other numbers supp**** by the previous number ***, *** and ***, i am still no further in actually upgrading my contract..Seriously. If you want to move over to a new system make sure it works.....
