Timewise their billing is not even close in timing to when the service is provided. I live out of state and used them to maintain an empty property every 3 weeks. They slowly tried to ramp up the schedule to make the cleaning more often thinking I wouldn't notice. Also, I guess they thought because I was out of state that no one would be checking the quality of their cleaning. The results: cobwebs and dirty baseboards for $90 every 3 weeks. They also did not bother to mention a $5 surcharge for taking a credit card - they just tacked it on.
