Debit order deducted after loan paid up

My Direct Axis loan was paid up in full in January 2022 yet MBD deducted a debit order from my account on 12/03/22. I had sent an email to Direct Axis on 07/02/22 asking them to stop the debit order yet you have taken my money again. I contacted Direct Axis immediately after the debit order was taken but the lady was unhelpful and said she would refer the matter to a Manager - obviously no reponse from Direct Axis Management. I have sent emails to the accounts department and the complaints department but again no response. I see this is a common occurance after reading the reviews of Direct Axis and MBD but I will not let it go - I want a refund this week or I intend to lay a case of ***** and report this to the Ombudsman. If everyone who has problems with Direct Axis was to report it to the Ombudsman maybe then they would get their act together and stop trying to ***** people's hard earned money.
