Bad attitude from the lakeside branch called Nothando. I was waiting outside the branch as there was loadshedding, the power came back and I asked her for a bank stamp as I was rushing to go submit my documents but she rudely told me that the system is not up as yet, when I politely asked her what does the stamp have to do with the system she told me that for that she won't open the roller door because I'm too forward. I honestly don't know if this is the customer service we will get from capitec and unprofessional consultants that think they've made it by working at capitec. Can Ca
