Using leaf blowers to blow litter/trash

K&S Greenday Inc. performs "property Maint." for 40+ WaWa Stores in NJ. One of which I own property adjacent to. K&S Greenday weekly "MAINT." of the lot consists of nothing more than 2-4 workers using blowers to blow litter/trash/dust/debris out of the parking lot into the surrounding area...very RARELY has K&S Greenday actually collected and disposed of the litter/trash/dust/debris as they should..highly unprofessional.
