Appalling LTE advanced speeds

I recently purchased the Cell C LTE-A through Webafrica. My reason for this was so that I can stream content without issues. I could not have been more wrong in my decision. This has to be the worst LTE I’ve ever experienced. At best I’m able to get 6-8mbps. During the evenings the service just stops working completely. This basically means I’m paying for something that I can’t even use. I’ve moved around the router and ran the speed tests with an Ethernet cable ensuring no other connections. The speed is still appalling. I’ve tried placing the router higher up and this still doesn’t help.

Phoning through to Webafrica is another mission. The waiting times are insanely long. I am really inclined to now cancel this completely.
