Salesman knocked on my door loudly despite having a “No Soliciting” sign; he knocked so hard it actually sounded like he tried to kick the door in. Then would not leave my porch for over a minute so my dogs continued to go crazy. Had to excuse myself from my Zoom meeting to go get rid of him. People work remotely and have no soliciting for good reason. Completely unprofessional. If they are this inconsiderate before they have your money…
