Very unhappy client

On the 30th December just after 23:30pm we had a power failure, at the same time I was withdrawing from the atm machine located at Engin garage in Belgravia Road, Cape Town. As my money was about to be dispersed from machine the power goes off so did the machine. I advised the security at that time and was told to wait the money would maybe still come out but nothing. No receipt just a text saying the money was withdrawn but I received nothing. The very next morning I went to the Capitec Branch in Athlone, I advised them what happened they then called head office or thats what they said. I was then told to wait 7days as they need to investigate, its not my fault on what happened I told the advisor that its my last money were am i to wait that long. Im not very happy and ive been with capitec for long time now. Why cant they just reverse the money back. I must now go borrow money to put food on table for my kids as that money was to get them food. Its so unfair. Not very impressed. Up till today i have not received any type of notification or phone call. Its not very proffessional.
