********* practice

Great day

I had an Fnb account whilst still working, the last time i worked was in March 2017. The last time i used my account was in 2018 and now it came as a shock when i app**** for funding and they wanted my bank statement it shows that i owe R-3972.55. How iam i expected to pay this sice i actively stop receiving active salary March 2017? I find this to be financially ********* practice, i want that account closed and will not carry the costs as i were not informed that the account is still active. It is the bank's responsibility to know the information they have regarding the customer's current situation or status in order to be update and record information that is accurate. Is this how Fnb treat its customers??
