Refusing to clean bin on bin day

Today is the second time in a month that the guys who clean bins on bin day refused to take our bin. Tonight they arrived at 9pm at night , cleaned every other bin around but refused to clean ours, we have no waste that isnt allowed ,only the usual bags filled with waste. <br> <br> The one guy looked at the bin from outside and kept on with others.This is outrageous due to the fact that it promotes an unhealthy area and attracts flies. This is unacceptable and needs to be dealt with. <br> <br> This happened 3 weeks ago as well.
