Stament problem adding money

I think as client we need to double check your statement from this company. My installment is R 943.00 which they are debating my account which is R 1000.00 every month my account is up to date and today I received an amount of R 63.63 as arrears interest instead of them owing me i have to be charged R 63.63 almost every month I have to get this.i have query this in December. I think as client we need to double check our statement.

Am not happy at all with this bank. I will never go back. I called them now . I already spent R 30.00 of my airtime am still awaiting for the supervisor to call. Statement was forwarded to me today at 15h15 from African Bank. That is why am not finishing paying them because they keep on add.

Thanks
