Account still open

On the 21st of may i called Direct Axis Call Center, a task that took 3 calls and over 50 minutes of waiting time, eventually i got through then i requested for a settlement figure for that day, in order to settle that account i was told it was 9698.33, then i requested to which account must I pay too, to settle this debt,, I was furnished with the relevant account, subsequent to that call indeed i made that payment, Today However i log into internet banking, the account is still in existence and on a negative balance for 526.47 nogal . I am not happy with this can someone please resolve this and explain to me what is the meaning of this amount and why is the account still open, 5 days after it was settled.
