I Need A Refund For Unauthorized Netshort Charges

I have recently noticed that my debit account has been charged weekly by merchants identified as “Netshort.g0mwirjl8c1u NA”, “Netshort.fz8y45bt80zm NA”, “Netshort.fyniwfijuhoh NA” and “Netshort.fzxxck1yfldt NA” without my clear consent or knowledge of any active subscription. These transactions started around 20 September and have continued on a weekly basis. The amounts taken were 17.82 NZD twice on 20 September, 44.98 NZD on 26 September, 45.95 NZD on 3 October, 45.25 NZD on a later date and 45.59 NZD on 10 October, reaching a total of 169.32 NZD plus an additional 45.25 NZD. I do not recall knowingly purchasing any ongoing service or subscription from Netshort and I was not informed about any weekly charges. I only became aware of this situation after noticing repeated deductions on my bank statement. I consider these charges unauthorised and I am concerned about the continuation of such debits. I request that all payments taken by Netshort, totalling 169.32 NZD plus 45.25 NZD, be fully refunded to my account and that any existing mandate, subscription or payment arrangement that allows Netshort to charge my debit account be cancelled and blocked so that no further payments can be taken. I also ask for a written explanation of how these debits were set up and under what authority they were processed. I kindly request that this matter be investigated urgently and that the necessary steps be taken to protect my account against any further unauthorised or unclear charges.
