Horrible Signal and Customer Service

<p>I have a Vodacom contract and use an enormous amount of data, yet it always tells me unable to connect or you are currently not connected to the internet??? How is this possible? I use about 3Gb of data yet I cannot go on the internet and have to reset my data connection. Also I have requested a voicemail function a month ago, and still I have no voicemail when I dial 121 it says your request has been logged and will be activated within 24 hours, this has been a very long 24 hours. I run a business and need my data and voicemail to work. This is pathetic!!!</p>
