Poor customer service

Poor customer service at one of your branches in Pretoria cnr madiba and old andries street. I have went to that branch twice around the same time on Saturdays they told me same story that they can't help me because their system if off line but and they say we can try bloed street. And the one in bloed is always full I don't know if is because the service they offer and sad thing is I couldn't activate my app. Because I work in retail stores I don't know when I will be able to get back or get a chance again
