DISGUSTING support from FNB after I have banked with them for 50years

Have had an account with FNB for almost 50 years. Unfortunately, everything has been taken away from the branches and it is now almost IMPOSSIBLE to get any action from FNB. I have an amount that was reserved in my savings account, and due to this i did not pay any banking charges. FNB then in their wisdom without consulting clients increased this balance by R5000.00. As i was not happy and decided to cancel the arrangement and transfer the amount out of hold as required some of the funds for other uses. It has been impossible to get FNB to take the hold off the account, they will not do it on phone or online, so I have so far been into a branch twice so far to have this hold removed. They seem to find this impossible to do!!!!!! Last visit first consultant could not get this right, then was referred to another consultant, whom I spent over 2 hours with, she spoke to over 20 people who were unable to assist. I was then promised that it will be attended to. However, it is now over a week later and this has STILL not been attended to and I AM STILL UNABLE TO ACESS MY FINDS Have tried every avenue, but the FNB staff are obviously not trained properly. Not sure where to go next? Maybe the Chief Executive? Can't believe i have supported this bank for v50 tears to be treated like this!!!!!!! J.M Ritchie
