Standard bank student account

I was a student with a student account with Standard bank, and a debit order kicked out and they never made me aware of additional fees and overdraft charges on a student account. After months I barely use my account because I'm a student we always broke ... standard bank ends up charging me close to R1000 and they keep adding. I spoke to the manager and told him I dont have the money and I cant afford this as I still have my campus fees to pay and they refused to stop the account from gaining more overdraft charges. Now they not responding to my emails and they still charging me on an account I dont use . They are ruining student accounts for students and robbing us of our money for our education because of their selfish motives.
