Canadian Property Stars

I got a knock on the door last week and a Canadian Property Stars crew was doing some work down the block and asked if they could do work for me while they were in the neighbourhood - they had a lawn aerator and a power rake. I agreed to let them do my lawn and when they were finished there were three large brown yard waste bags on my front curb filled from the power raking. (The pictures show two bags but there was a third one on the other side of the walkway leading to the street.). I thought they put them on the front curb because they were going to come by to pick them up later. Several days later the bags were still there. I called their number, (I am in Vancouver) and I spoke to someone in Ottawa. They said that they do not pick up the bags. What am I supposed to do with these bags now. If this was the case it would have been better for them to put the stuff into my green bin and saved themselves three brown paper bags. I am glad that it did not rain and get the bags all soggy since now I need to take care of them - DISAPPOINTED that they did not finish the job
