Wifi not working and Telkom not helping fast enough.

Wifi went off this morning. Spoke to consultants that tried to help and one told me to reset the router. After setting ppp0e and checking cables, the other consultant said it might be an authentication problem and logged a fault and said someone would phone back but could not say when. Tried phoning telkom a few times afterwards but could not get through and even phoned the D-link no, they were unhelpful. It is 9pm and still no wifi connection. I was on leave today and spent almost the entire day trying to get the wifi to work. Ref no ***0
