Frustration experienced with network

I wish to make a complaint against Vodacom. I am constantly subjected to extreme frustration of the inability of their network to function correctly in the area I stay. Also this frustration is not confined to my area. When I try and download something from the Play Store the download starts and then gets stuck which results in me restarting the download thus losing data. This is a reoccurring problem all the time. Also I would like to know from Vodacom if a person earns still earns talking points from putting on data and if so how come a message is no longer displayed informing that.
