At American Express Europe S.A., I analyzed suspected fraud cases for private and business customers, reviewed transactions for anomalies, and initiated preventive measures. I also contacted customers by phone and in writing to clarify suspicious account activity.
I documented case files in the CRM system in line with compliance requirements and followed strict data protection and security rules in banking.
At E.ON Energie Dialog, I advised private and business customers on electricity and energy tariffs, terms, and contract changes. I actively sold tariffs and regularly exceeded my personal sales targets.
Earlier, I supported O2 business customers with contracts and mobile products at TGCS RostockGmbH, and provided first-level DSL and internet support at KDW Greifswald. I diagnosed connection and device issues, advised customers on O2 tariffs and accessories, and supported product extensions and upselling.
