Trying to Change my Address on the system

I have an address on my FNB Account and it has been wrong for over 10 years as everytime I try to change it, the call centre as well as the banks cannot help, <br> <br> I took the only proof of address I had with me to the bank today, sat there for more than an hour before being helped and then they couldnt change my address as I do not have proper proof of address.<br> <br> I use my FNB statements for proof of address and I cannot anymore as they have been wrong for like 10 years.<br> <br> It is ridiculous how they wont accept anything<br> <br> I even sent an email to [Email Removed] waiting for feedback now, doubt they will help either
