We are very, very grateful to "coretress GmbH" for your quick and very professional help!
Unfortunately, we previously had to make very bad experiences with an online information systems GmbH in Oberberg. Due to an unprofessional, professionally incompetent and humanly empathetic approach after a hack attack, they were not only unable to help us at all for several weeks, but also caused us great damage both financially and emotionally due to blatant errors.
The experts from "coretress", on the other hand, had an immediate solution at hand due to their outstanding, professional competence. They immediately freed us from the evil and additionally helped us to a secure system for the future.
The professional competence impressed and inspired us, the very personal and visionary advice made us look into the future with more confidence again, but above all the very high level of empathy and understanding quickly took away our despair and gave us back a good feeling.
Many thanks!
