Not updating/changing

I have emails so many times and no one is bothering to come back to me why!!! Sassa came to Leisure Bay last year twice and twice i have given them all my correct paperwork to change from sassa card to bank account and nothing being done, are they throwing my paperwork or what. I can not drive to port shepstone as I do not have a car. I am deaf I can not phone. Please I am asking so nicely to please update my info. I want my grant to be put into my bank account. I have tried the website it not working it keep lagging. Nothing is working. When I log onto the website I see it still under old name which tells me that the people that came to Leisure Bay never update my name etc. I thought sassa was suppose to be helping people those in needs but obviously not. I am sorry for being angry but it so unfair on why must I keep fighting for my right for help.
