UIF email clearly doesn't work!

You complain that you only have 40 agents answering 77000 calls per day. Your lines at your branches are around the block, it doesn't matter that a person is there before you even open. Come lunchtime you close the line even though you only close at 16:30? All I need to do is actually change my bank details because I have sent it via your email portal 16 TIMES... yes 16 TIMES and NOTHING. If I don't change my bank details then ABSA bank takes my money. So please tell me how the hell are we suppose to live????? NOT IMPRESSED
