Coles Supermarkets / abandoned trolleys

Once again Dundebar road Wanneroo 6065 Perth WA looks like a mess again with all the Coles Trolly's littering the street.
There are at least 9 of them on both sides of the road by the Council Offices why can't the trolly collection team collect them every couple of days instead of leaving them for sometimes at least a couple of weeks.
Could you please inform the Wanneroo store as it is their responsibility to make sure our suburbs do not look like a tip.
I understand that some of the human race are lazy and Coles cannot do anything about that but they have spent money in the store so the least Coles can do is relieve us non lazy people of the unsightly mess they leave on our streets.
