Disgusted

I am utterly disgusted with the treatment ive been getting from nedbank, i posted a querry a few weeks ago about my grandmothers account and a very helpful lady responded and gave me great assistance. the last email she sent me stated that i needed to take a proof of residence letter to the branch which i did on the 4th April 2015. when we got there we were told that my grandmother needed to get a new i.d, mind you there is nothing wrong with it nor has there been any tampering on it. finally they decide to accept it and say i need to do a follow up. i did a follow up yesterday and was told they will get back to me. they did get back to me today and im told that we need to bring the same documents in again even after explaining to them on Saturday that i do not live with my grandmother and as she is old i have to hire a car to get her to the branch. i enquire about just closing the account and i am told that they have no plans of keeping it open, they will be closing it. i am disgusted buy this as i havebeen dealing with this case since January
