Request for Account Statement and Dispute of Unauthorized Debit

We I am writing to formally raise a concern regarding my account with Nimble Group. It has come to my attention that a debit was processed from my bank account in January, despite the fact that I had already settled the outstanding balance in full. My final payment was made in November, or possibly December, after which I understood the account to be fully paid. I have been consistently monitoring and tracking the balance of this account since I began making payments, and I am therefore certain that no further amounts should have been deducted. The recent debit is both unexpected and concerning. Kindly provide me with a detailed statement of my account reflecting all payments received and the current balance. I request urgent clarification on why a debit was processed after full settlement, and I ask that this matter be investigated without delay. Your prompt assistance in resolving this issue will be highly appreciated. Yours faithfully, Letlhogonolo
