Data gone!!

This is now the 3rd month that both my wife's and my phones data is finished and it's only the 3rd day! We have each been using the same smart phone for the past year and none of our settings have changed! In the past our data on our contracts lasted at least 2 weeks and now we've both realised that Vodacom is *****ing from us. Our router, of 10gig also only lasts 1 week! An absolute joke. We have been with Vodacom for 12 years and am definitely considering moving to a more honest, and trustworthy network. We were on holiday and the data disappeared of our ****le. I cannot believe that Vodacom is allowing this to happen!!! Very disappointed with the network I've supported for so long!
