Yard Issues After Telus Digging – What Should I Do?

I live in a 25-year-old house in central Alberta, and after about 18 months of living here, we've run into some serious yard issues. In November, Telus began digging in our yard for new fibre optic lines, using hydro excavation for several days until about a foot of snow covered everything. They left some equipment and plywood under the snow and continued returning every few weeks, with some of that time seeing extreme cold temperatures of -25/-30. Now that the snow has melted, I've discovered major problems. My front door is sticking, the stucco near the door is chipping, and the door frame is visibly bowed. The yard has pulled away from the sidewalk and driveway, creating a 2-inch gap, and there are cracks in the sidewalk that have widened significantly. Inside, there's a 2.2-inch gap between the floor tiles and the door frame, and the driveway has also pulled away from the garage with a 4-inch gap. I've noticed spots in the yard where the grass is missing and large holes have appeared. None of these issues existed last summer. I've contacted several contractors and a geological engineer, but they won't be able to come until midweek next week. I'm really lost about what's going on. Could this all be linked to the digging by Telus, or is it something else?
