Vodacom mobile app always off line

I'm at my wits end with the Vodacom website and mobile app.It's has been my personal experience that both are more off line than working. Viewing your bill online or buying data bundles have become impossible to do Calling the call centre is futile as you get sent from pillar to post and you are made out to be the stupid one. This has been ongoing for the last few months and they're always saying they are upgrading their website for a better experience. What a load of tripe. Not even falling under the mighty Vodafone umbrella helps this bunch its all just window dressing.
