The so how can we help you bank

My experience by far has been very frustrating, I lost my husband and now FNB is just adding in my emotional toll, been to branches for assistance, they have tried to assist me form branch level unfortunately my matter needs to be attended from else were which is their Deceased estate department, all I want is to close my late husband's accounts, who is supposed to help, till today since last year the accounts are not closed. My husband's account ID accumulating charges while wait for the incompetency of someone who is not willing to assist.
