Pathetic Service

Customer Service.... non existent. I am on the verge of switching banks. I tried to up my credit card limit on the mobile app, I fails as I do not qualify. Then I tried on FNB online banking and it says success but the limit never gets updated. I call the call centre and they require my signed document and payslips which I sent through. I had no response or acknowledgement that the mail was received. I phoned ********** 111 the 1st agent said I would get an sms and the limit will be increased. Instead I got an e mail requesting all the documents again. I called again to follow up and the call was answered, but no one on the line, I can hear personal conversations going on. Dropped the call and redial 2nd time in a row, I hear the agent talking to his co worker about what cars to drive and what not to drive, so I drop the call again. 4th call I get put through the the Auth process, as I get back to the agent I get put on hold for 5 min. I dropped the call again. Still no outcome.
