Vodacom network connection sucks

Vodacom network sucks. For the past 2 years I have been calling their call centre complaining about their nonexistent network connection, but nothing has changed. Instead their network connection is getting worse day by day. It seems like they don't care about us being their customers. As long as they rip us off our money by taking our data whilst we don't even have a connection they are fine. Every time I call them they pretend to be fixing whatever problem they have, but honestly they are not doing anything to solve this. Maybe I should consider using better network providers. I think I have been more than patient with this kind of nonsense
