Poor customer service from Huawei

I recently bought a Huawei wifi router that is supposed to have a 6-hour battery life, but it doesn't. It's done in 4 hours. The setup instructions inside the box are also incorrect - the IP adddress doesn't work. Luckily, a friend knew how to work around this. (Her solution isn't even on Google as a solution.) I informed Huawei via X. Their response? Speak to Vodacom because that's where it was bought from. How is Vodacom supposed to fix what are clearly their errors? I will NEVER purchase or recommend Huawei to anyone else.
