Very Bad service

I went to the Capitec ATM in Sandton to withdraw money, R400 and I followed the withdrawal process but when the machine was supposed to dispense the money it didn't, yet I got the withdrawal notification and machine immidiately went out of order.... Mind you there were people working on the machines inside and there was no notification of this. Luckily I used the ATM outside the bank and I immediately called one of the consultants to assist, she asked me to go inside but when I got there I was told of an investigation that would take up to 48 hours. This is money for my transport for the week for work and these people don't seem to care, while I wait for this investigation how will I be travelling to and from work. It's about time I changed banks. I've been with this bank for about 12 years now and this is the s**t service I get
