Paying for service provider's sins.

I logged a dispute with Cartrack in December after they did debited my account a week earlier than agreed. This resulted in my debit order being rejected by my bank costing me R105 penalty fee. The debit order was successful a week later on the correct date. I have requested the penalty fees from Cartrack since this was their mistake and they've dented my credit profile as a result. The matter has not been resolved. Please assist me.
