Frustration

I haven't been working for a year and 7 months then i had to apply for a job where they needed my bank statement. I went to stand bank for my bank statement, when i got there i found out i owe R1000 so on the same day i asked them whats going on as i haven't been working so where do these changes come from, can they plz stop the account so that the money does not keep on adding up because im not certain im going to get a job anytime soon. They said they cant close the account bcoz there money is owed to the account after countless attempts.I asked them is it possible to speak to the manager they informed me hes not around and referred me to the other consultant i told her my story and she made a call to the head office of standard bank so that i can tell them my story which i did then he said i should come back after a week at the Lenasia Standard Bank branch they going to go through the account, of which i did go back a week after the standard bank branch didn't have answers for me.The guy that was helping me called the guy from the head office i talked to him and he remembered me and asked me to take down a email address which i must send to my branch where i opened the bank account in this case my branch is in the Free State in Kestell, so that they can cancel my account so i asked the branch in lenasia which i was currently in to send my document all of them including my affidavit stating that i haven't been working so could they please stop the account and i even gave them the email i got from the head office at the branch we tried calling the manager of Kestell but he was not around so the consultant said she will call him, she knew my story then i left then she called the next day telling me that they say they cant close the account that is what the Kestell branch said. So i was at home at that time i got the numbers for the Kestell branch in the free state and i called them, i spoke to the manager because he already had my documents he told me that they cant close the account because i have signed that im going to look after my account, i asked how did the money accumulate on my account and where are those charges coming from ? He told me i need to come in so they can check my account for me, i further explained that im no longer residing in the free state i have relocated to Johannesburg, so how do i then come in for them to assist. I asked the manage if its possible that that account be stopped and i no longer want that account and can he please look into my account and call me to give me feedback. while the money was still reflecting in my account i have tried to go to the standard bank near me no one seems to know what i need to do i was even given a number to call to complain about my issue. I had already stated that im unemployed and i would like to find out what is going on on my account and im not getting any assistance i get sent pillar to post and i fail to understand why i need to go to the free state just for me to get clarity while every standard bank is supposed to be able to assist regardless where i am. Two days ago i got an sms from standard bank threatening to take legal action on me for the amount owing on my account. i have not received any feedback from the branch and yet i get this now and still i don't understand what is going on and it seems like no one seems to explain and now all they want is for me to pay money that im not liable for. Can someone please help me with this issue.
