Customer satisfaction

Our customers’ satisfaction is important to us. It's very important to us that our employees provide our clients with personalised and individual advice and support.

Excellent service

We're delighted about the many positive messages received from our clients. Every year, up to 70,000 randomly selected clients rate us online or by phone (in a survey conducted by the 'AmPuls' market research institute). This feedback is extremely valuable to us. We constantly learn something new, and this contributes directly to the ongoing improvement of our products and services.

It was quick and easy. I went to the CSS office and the staff were very friendly and helpful.
