Poor service

My husband deposited the amount of R10,700 on the machine then R200 notes was rejected by machine. The machine was busy processing to our surprise slip come our with message not successful. He waited infront of the machine nut the money didn't comes out we went inside the bank Yota the manager was telling us about procedure to follow. Then we even indicated that the is for the fees as if we don't pay by 1st the will be accumulation of interest. Then she phoned head office then the lady who suppose to balance machine will do that then they wll see if the issue will be resolved. The manager saw the frustration from my husband and he was not Okey. Should anything happened to him health wise I wll blame FNB. He was so frustrated couldn't talk when he was supposed to fill the form stress is the amount that was taking machine worse the was no help. If we are encouraged to use ATM then at the we are suffering while it's our money is not right. Can this matter be resolved because people are attacked by strokes or heart problems because of not being able to handle such stresses. The manager YIta withnness the frustration as trauma to my husband. So FNB must resolved this issue because we wll be facing interest on my. Child's fee and some debits order will not get the money because of FNB problems.
