First of all I find it facinating that the reviews for this organization are either 10's or 0's with only one in between. It suggests to me that either this company is capable of doing great things but only for a limited few or that the psoitive reviews are not in fact real.
My expereince seems to be more with the majority - very dissatisfied. I too purchased 3 2-hour sessions. When I tried to book a 2-hour session I was told it would be months before they could come - HOWEVER, if I wanted to pay an additional $100, to do an entire house clean, they could come within days. I sprung for the extra $100. When I tried to get dates booked again I had problems - emaisl were weeks in being answered, phone calls were never returned. When the cleaner did arrive, she had no tools or equipment of a professional cleaner - a bag of rags and cleaning supplies and a portable "dustbuster" vaccuum. Not the "professional" approach the company's web site suggetss.
Overall I found On SIte to be lacking in quality, customer service, and integrity. Stay clear of these poeple. Definitely do not deliver what they promise. And do not fall for the upsell.
