Unhappy vodacom client

I have been STRUGGLING with my Vodacom router since the day I got it. The speed is definitely not what it’s supposed to be. One minute you’ll have signal and the next minute the signal is gone, which causes you to have to restart the router. That is even worse than the internet, according to the manual you need to keep the button in for 3 seconds, as soon as you think the router is going to go on, it shuts off again. I have been trying to get in contact with Vodacom via telephone and email, following up on email and still no response. I have to pay for something that I’m unable to use. This is outrageous. I understand that I’m just another client to Vodacom but there is absolute no customer service.
