Technology
As a Vodafone customer I find their network robust with good coverage in the most bizarely unexpected of places where mu chums with other quality networks struggle, Vodafone has made an exception with Lichfield for some reason where they seem to have forgotten to allow for coverage.
However do seem to have forgotten there is more to their business that an audio network and struggle with the associated technology.
Their website is laughable, the "my account section" specialises in 3 clicks where one would do and hides important info in obscure places. In fact the website is a trip back to early business type sites.
Their billing has been so poor that a random number generator may be more accurate.
That is only two and I am stopping now before I go into full rant but can they not employ someone who understand these other aspects of their business and improve upon them?
