Car installments

My name is Jabulani Ngubeni and I have a problem with my vehicle finance December I missed payment and only realized end of January and on the 03/02/2023 I paid R11300 for arrears but they told me account department has not rectified that and after 2 months they stopped deduction on my account and I was on arrears again they called and I asked for the account number so I can deposit the money but they never sent it but after a month they started again deduction on my account for the car payment and now last month they didn't deduct which is why I'm writing this now because I feel like standardBank is on a mission to reposses my car but I really don't get it why there's no consistency in deduction because I gave them the date of deduction but it's not happening like we agreed please assist on the matter I don't want to loose my car
