Vodacom online site is forever not working properly wasting customers time & money.

It's amazing how such big IT corporates forever have issues with their online sites. I'm trying to view deals for upgrades and in the past few days keep having error such as "We seem to be having some issues loading filters right now. Please try again later." and "We seem to be having some issues retrieving your recommended deals right now. Please try again later." Not acceptable!
