Callexcell is highly appreciative of its cooperation with THoCC and its consultants. Callexcell has expanded considerably and THoCC has helped us manage this growth in a very professional and profitable manner. The operating model's 54 processes are the perfect compass to navigate all departments in the same direction and to set the right priorities at any given time. THoCC's consultants relate to the situation and problems of their customers and end customers very well. I would definitely recommend THoCC to other parties.
