UNAUTHORISED DEBIT ORDER DATE

MBDLC repeatedly fails to change my debit order date, as discussed via telephone just a week or two ago - I have also sent emails to them requesting the same. I did not give you permission to run a debit order on the 10th of the month. I am asking you one final time to please change the date to month-end. This is extremely inconvenient and causing me to have a poor history on my bank account. I've also told you that any income (UIF and temp work) is paid into my bank account at month end - I might now be forced to inconveniently close my own bank account because you don't care to follow a client's request.
