Worst wifi in existence. Stay away!

Been battling for 3 months with wifi. Wifi reception goes on and off the whole day,and when it works it struggles to perform over 2/3 mb. It's more off than on anyway. Zero support from support line. They take days to respond,and when they respond they cannot fix the problem. Have spent over R1000 in mobile data in the last month as I have resorted to hotspotting from my phone.
