Called a week ago for the opening of the gas meter. I asked the operator THREE times if he needed documentation and he replied that if there is a plumber I do not need anything, they give me an appointment from 3 to 5, they arrive at 4:50 and I do not open the counter because the camera is missing and the model b12. The operator also quite "phenomenon" and rude. We are at December 20th and do not add anything else.
