Unhappy ex client

I am so disappointed with standard bank received an SMS right now advising of an active accounts which I requested account closure on in January last year I was not aware this account was still open.today when I received an SMS saying that I must update my figure documents I must bring my ID and proof of address for fica purposes and now they telling me I'm supposed to pay that service fee that has accumulated for over a year in the account accounts that I requested closure for,but only a fixed deposit was closed now I am in distressed I'm unemployed I won't be able to pay that and they telling me that I should pay it. why am I eligible to pay for something that I requested account closure for I am really really disappointed I loved this bank but now the way they do things it's not fair...I've been to a branche and also called the call center no one can assist me simply because there was no account closure stated for the other accounts , only for a fixed deposit while I said for all my accounts I need them close
