Unauthorized Debit From My Account By NetShort

I am writing to report a series of unauthorized debits made by Netshort from my Providus Bank Debit Mastercard, even though I do not have an active subscription with them. On 24 August I was debited NGN 7,083.02. This was followed by NGN 35,243.19 on 30 August, NGN 34,651.47 on 5 September and NGN 34,992.00 on 12 September. These transactions, including one reference to Netshort.fy194tt5q7tl, were all taken without my consent and without any subscription or service request from my side. I have already sent several emails to Netshort attaching proof of the debits, but I have not received any response at all. These repeated unauthorized charges are seriously affecting me, as the money being deducted is what I need for my weekly medication. I request that Netshort immediately investigate this matter, cancel any unauthorized subscription or service linked to my UID 59023106 and fully refund all the debited amounts to my account without delay. I also expect written confirmation that no further charges will be made to my card.
