Quick CALL task to GMX customer Service for a German speaker

I'm seeking a German-speaking professional to assist me with a GMX customer service call. The primary purpose of the call is to change some account details. More specifically, this involves unlocking access to my account by confirming its details.

Key Details:
- The task essentially involves confirming account details ( name, date of birth, payment method used, etc ).
- Proficiency in German is a must as the call will be with a German-speaking customer service representative.
- A calm, professional demeanor is necessary for dealing with customer service.

This is a straightforward task, and I appreciate your professionalism and discretion in handling sensitive account information.
