Incorrect debit order date

I am very disappointed by the manner in which Cartrack conduct its business . I have a debit order which was returned unpaid due to insufficient funds and incorrect debit order date. I have accumulated bank charges of R147.00 with standard bank. Cartrack also did a debicheck on my account without any arrangement for the second time. I am requesting cartrack to refund bank charges accumulated . R294.00 needs to be refunded.
