disregard of the elderly

hi my dad has been with you guys for years having his salary being paid in this cheque account and when he retired 5 years ago not even one person from customer services called him to inform him of the type of account he has is a bit much for a pensioner he was diagnosed with dementia and cant do anything for him self and as we speak he is no his death bed i as his son has being looking through his policies and guess what all of them has been behind because of standard bank due to insufficient funds in his account from cheque account monthly fee and unpaid debt orders he now does not have any death policies and we as a family do not know how to over come this how can such a huge establishment not notice that this old man is paying too much on this account that is why his debt orders is not be paid this is a big concern and i will be taking it up with the banking ombudsman and the media including hello peter this is such a disgrace coming from the Promenade Branch Manager
