Bad service from Standard Bank Vehicle and asset finance

I'm very displeased with Standard bank vehicle finance dept. After buying a vehicle a few months ago, I had 2 successful debits from my bank account. I did a large capital amount as well. Due to a system error the next premium didn't go through. Standard bank handed me over to some 3rd party debt collector. They have since taken the next premium through a debit. My next debit date is 24 December 2025. Daly (Whatever they call themselves) keep hassling me unwarranted. If I were someone that didn't want to pay my installments, I would really not have paid in a large amount as well. I am very dissatisfied. Thank you Standard Bank and Daly for making me feel like a ********.
