The company that tells you "they not know what you expect them to do" when their equipment isn't working!
I've been experiencing this error 30 on their prepaid meter for the past 5 months, its always a battle to just to load electricity and when you call them their staff is not helpful when explaining the situation and the duration of this issues - they'll tell you they don't know what to do (full stop) without giving you alternatives - consultant name: Gift Mkhonto - Time of call 06:50, their service delivery levels are horrible and customer care competency of their staff is totally unacceptable.
