Unauthorized Transaction Complaint Letter Template

I need a crisp, legally-sound complaint letter template that a customer can fill in quickly when they face an unauthorized or fraudulent banking / UPI transaction. This document will be the first downloadable template offered by ResolveDesk, so clarity, accuracy, and a professional tone are critical. Scope • Draft one reusable template addressed to a bank’s grievance redressal officer or nodal officer. • Build in clearly marked placeholders for customer details, transaction reference numbers, dates, and the exact debit amount. • Reference RBI regulations on unauthorized electronic transactions and the customer’s right to a reversal within stipulated timelines. • Keep the language firm yet courteous, suited to both email and printed letter formats. Deliverable • An editable Microsoft Word (.docx) file and a matching PDF. Acceptance criteria • All mandatory elements (subject line, account details, factual narration, loss statement, relief sought, and escalation notice) included. • No spelling or grammar errors; reads smoothly on first pass. • Formatted with consistent font, margins, and line spacing; placeholders clearly highlighted. Once approved, I will slot the template straight into our website for instant download, so minimal post-editing should be required.
