Fixo - non existing service

Marius Muller is the owner of Fixo who ‘specializes’ in installing solar energy. His pre- service levels is good UNTIL he got his payment. The after service is shocking and non existing- he makes appointments and never pitch- after receving full payment UPFRONT and the system still not function correctly???? Also get paasive aggressive if one dare to say or compain aboit the non-existing service. Don’t make use of his services😡
