ProStar Cleaning

I hired these guys to clean my rented two bed room <1000 sqft cando for move-out cleaning. Two women were sent to attend my appointment and they both spent 4:25hrs. The Prostar charged me little over 400CAD. But the Prostar people did a terrible job and not worth even half of what has been paid. It was highly unprofessional and even I reported this but no use and no response. If I could give negative rates I would give -5 stars for their horrible service.
