UNAUTHORISED DOUBLE DEDUCTION OF MONTHLY DEBIT ORDER

Talk about frustratingly poor service - they take the cake!! I have a COVID Loan which was taken out in 2020. I have a debit order which is automatically deducted each month on my payday. Suddenly they take it upon themselves to push through 2 debit order deductions each month as from January 2023 (which was never approved by me). Despite hundreds of emails and promises of them looking into it - NOTHING has been done. Each month I have to reverse the one deduction, which I incur bank charges on and this also negatively affects my credit rating. Cannot believe how they are allowed to operate like this!!!
