VODACOM DATA RIPOFF ARTISTS

Has anyone tried to contact Vodacom to lodge a queiry? It is impossible to get to talk to anyone HUMAN on their site. I have a phone that connects to my wi-Fi for 5 minutes then proceeds to go offline and chew through the data on my phone. I have perfectly good Wi Fi but if I want to use it I have to constantly turn off my modum and restart for my phonr to connect for another5 minutes. Do you think I can get anything other than the stupid BOT TOBI telling me to BUY MORE DATA. I have tried everything to get to talk to a human at Vodacom as I should not have to buy data when I have ample ****** WIFi. Duarenteed I will not hear from this useless lot .
