The owner arrived at our EMPTY two bedroom condo for a move in clean. He texted a quote of 5-6 hrs for two people (so 10-12 hrs) and asked if we wanted windows done also. I agreed. I then got a bill for 16 hours, or almost $700!! For an empty condo which had already been surfaced cleaned. There is no way the windows took an extra 4-6 hrs especially because they weren't fully cleaned (presumably they stopped at the height that they couldn't reach) and other . I emailed them about my disbelief and got no reply. I emailed again and a response in which he fabricated about what happened, in terms of timeframe and accused me of misunderstanding. I have the text and email proof, however, and he also said that he "assumed" I wanted it fully cleaned.
