Card number ***

I have a problem with Eskom, my dad is a pensioner and they recently installed electric meter at his house and was told to register or activate his card at nearest Eskom. We have been to several Eskom offices since then sent back and forth fill forms but till today the card has not been activated. I phone and emailed their customer care line only given ref number ********** 02 but never got help. My problem is that I can only buy electricity for him only at eskom not at retail shops or banks since the cards is not ectivated and Eskom only operates during office ours and I am at work during the day. Please help me the old man has lost hope and sleeps in darkness.
