Metro Snow & Ice Management

I hired this company and haven't had an issue until Sundays' storm. City plow went by Monday at 6:30am... I had to be leaving for work at 7:30am and ended up shoveling the thick city crap myself. I saw the plow come onto my street as I pulled away. SO in their fairness, they came after the city... and I can appreciate they have alot of customers will all that dump. They cleared the part of the driveway behind our second car. As with all the other snow falls, I expected them to return in the afternoon to clear the rest of the driveway. I came home and it wasn't cleared... and they never returned. I have not been able to reach the company and I have left many messages. I want to give them the benefit of the doubt that it was a huge amount of snow.... but why didn't you come back later that day?? I ended up having to shovel 2/3 of my driveway to put my cars back in. I hope this isn't foreshadowing my evening tonight.
