77 Year Old man on the street due to Standard Bank's complete inefficiencies

I have never experienced such pathetic service from a bank. They do not phone you back, they don't answer their calls and they don't reply to their e-mails. This has now been months of trying to get them to do their job, with nothing forthcoming. They promise that the person they report into, will call you back, and then even that doesn't happen... Institutions like this should close their doors, My dad has been trying to finalise his estate since my mom past away two years ago. TWO YEARS!!!!!!! They don't want to give him a guarantee to the full value of his house that has been sold, which leaves a 77 year old man with a situation where is now physically without a roof over his head. YOU ARE THE REASON WE KEEP INNOVATIING?????!!!!! What utter lies and deception is this if you can't even return a phone calll??????? Your senior people Valerie van der Ster, Penny Bibby is absolutely useless to say the least.
