Why schedule staff at night if they don't answer the dam phones!!

Telkom **** service, I got a call from some cell direct telling me about my upgrade, I upgraded my Telkom router to uncapped via cell direct, it looks like my Sim card is not activated, I called telkom from 7h45 pm till 20h10 and they kept playing **** IVR music with no one taking the calls, I mean what the hell!!
