FNB: "How can we help you???". More like "How can we frustrate you!!!"

I have esscalated my issue with FNB and many of their departments, even having team leaders and seniors promise to address and resolve my issue of the FNB APP, 'PAY' option not working. I reported my issue to FNB 7 weeks ago. They like saying 'We sorry for the inconvenience caused'... This doesn't help! what helps is having the issue resolved!! How can it take your technicians 7 weeks to resolve this issue. Really really poor!
