discrepancy of settlement

I phoned in to request settlement of R12000 loan I made on the 22 February 2022 settlement is R 11863.31 while instalment of R1765.58 went off on 18 Mach 2022, why is the settlement is 11863.32 is your settlement charged with interest.

Every financial house quote settlement on capital amount without interest this amount can't be a settlement value and the loan is less than a month old

Please correct this
