Capitec bank ***** activity

I need you guys to fix my account please, on the same day you debited my account with the monthly repayment amount for my loan i tried settling my loan (by means of transfer) without even asking for a settlement amount, i couldnt settle because the app kept saying i am paying more than my balance, i only left R0,01 on the account due to that.. now i go and check the loan account on the app the following day.. to my surprise an amount of R700+ is reflecting as the balance on the account... nooo Capitec, i can't be held liable for a fault in your system that was not my doing.. i tried to settle by all means but your system could not let me.. please fix this i cant be expected to pay more for this account, that would be so unfair..
