Multiple times this winter they have neglected to shovel our sidewalk. Multiple people have called and they cannot figure out how to shovel the sidewalk in front of our condo after a snowfall. They shovel the driveway and courtyard, but don't shovel the sidewalks even though they are part of the contract and we've told them numerous times. I was shocked when I saw the positive reviews for them, as they are going downhill. This is for the East Town Condo Association in Milwaukee.
