Fraud Denied Dispute Analyst

I have a strong analytical background and investigate denied fraud claims for MasterCard – Access Prepaid. As a Fraud Denied Dispute Analyst, my job is to review every fraud dispute case which has been denied and the customer is not satisfied with the outcome. I ensure all global fraud disputes are managed in a professional, customer focused, timely and effective manner. I investigate all cases impartially on an individual basis ensuring all relevant information is gathered and considered. The role encompasses full administration, thorough investigation and timely response to dispute cases.I pro-actively liaise with key internal business areas and personnel including the Director of Fraud, Fraud Screening Teams, Managers, Legal, Compliance, Chargeback investigations, Product and many other departments to gather all evidence required to make an informed decision.I also liaise with police, merchants, acquirers and other parties involved with any aspect of a dispute to develop a clearer picture and to gather further information that the first party may not have provided initially. I take ownership of cases from inception through to completion and provide cardholders with full and clear relevant written responses to a consistently high standard if a dispute is to be denied. Part of my job will involve liaising with the Financial Ombudsman and legal (if cases go to court). I therefore have to make sure the decision is the correct one and that all aspects of the fraud dispute have been reviewed and considered. Part of every dispute reviewed is to understand how it took place in the first instance and try to combat this to reduce the risk to the business and the customer. Every dispute provides the opportunity to increase my knowledge and ongoing identification and implementation of process improvements (if required).
