Pathetic Fnb service

I am greatly disappointed by Fnb. I am sending this mail on behalf of my mum. A deposit was done by my mother in the 2nd last week of April 2019 and for some reason the atm did not register the deposit. She has been to the Gateway branch. Numerous phone calls and attempts to contact fnb have been unsuccessful and nobody seems to be able to help her rectify this problem. How can you have a motto saying 'how can we help you' if you fail to help when we need it. We are still waiting for Fnb to contact her regarding this query and this has happened over a week ago. Absolutely pathetic Fnb.
