double deduction on loan paid in April already!!!!

i have one loan with finchoice and the mobile loan(30 days) account . i settled the mobiloan in April 2019 already i paid R2267, but every month from April the money gets deducted. im sick and tired of finchoice making a deduction on money thatw as paid a long time ago, its affecting my credit score rating negetively. today is the last time i will be reversing the money and paying bank charges. i will report finchoice to the relevant authority or take up legal action agianst finchoice which will lead in them paying me more money that what i owe them. i have made 2 paymenta on the main loan account, they dont reflect, this simply means finchoice cheats and takes advantage of unsuspecting clients, this is wrong. stop making two deductions on my account and update my credit record to reflect i have paid the mobi loan.
