Per request, I had sent over pictures of the areas which had not been sufficiently cleaned over the first three visits; I received a phone call this morning offering a partial refund for the services due to the inconvenience and ultimately lack of job completed (they would have come out a fifth time; however, I had finished the cleaning myself rather than waiting.) I will say that their customer service is certainly attentive and responsive; however, customer service unfortunately does not equal a clean house.
