BAD WIFI

They are quick to up your payment almost every month we went from R338 to almost R500 now. We asked if we can down grade our line they said no, we asked if can cancel they said no, we've been using home connect for longer than a year now and all we have is problems every night... THE WIFI IS GIVING MORE PROBLEMS THAN ANYTHING ELSE EVERY NIGHT 5:30 MY WIFI SAYS CONNECTED WITHOUT INTERNET... SO WHY DO WE PAY SO MUCH IF WE CAN'T EVEN USE THE WIFI AT NIGHT.
