WASTE OF MONEY
Worst experience I have ever had. DO NOT USE THIS SERVICE.
I purchased a 2 hour clean through Groupon for what I thought was a great deal in January, 2012.
I initially made the appointment for Saturday Feb 11 @ 10am. I also informed the company that I had a flight to catch that afternoon, so the timing would be important. By 12:30pm no one had shown. I attempted to call to inform On-Site that I would need to reschedule, but could only reach an answering machine. The cleaner finally arrived at 1:15pm. I apologized (?!) and explained the situation. She told me that she would clean my place "really quickly". No thanks.
Upon my return, I attempted to reschedule. The rescheduling process was a ridiculous ordeal where a date was suggested to me over email and by the time I replied, the date was no longer available. I requested on more than one occasion to be contacted by phone. This request was repeatedly ignored. I attempted to call many times on my own and left several message. These were never returned. After over THIRTY email exchanges, we settled on a date and time - early afternoon May 12th (over THREE MONTHS after I first attempted to schedule an appointment!)
The cleaners arrived for the 2-hour clean at 4pm on May 12 (NOT early afternoon). After 40 minutes of cleaning, they informed me that they were finished. Since they were done so early, I asked if they could wipe down the table and chairs on my balcony. They refused and left.
The clean they did was mediocre at best - they only wiped down shelves that could be seen at eye-level, and completely ignored everything higher. They vacuumed but didn't wash the floor. They completely ignored my appliances. They didn't seem to touch my kitchen table. They left my toilet bowl full of dirty wads of toilet paper.
I did more work prepping for the clean than they did actually cleaning!
I contacted Nadinie Sidi, the Sales and Customer Relations rep, about my experience. She apologized and asked for a number where I could be reached to discuss things further. I provided my number, but never received a call.
At this point I was furious, but had no interest in interacting with this company further so decided to cut my losses.
Cut to November 2013 when I start receiving almost-daily spam from On-Site about new "deals". Giving them a final chance to redeem SOME semblance of credibility, I sent one last email explaining my experience. No reply. I may as well have flushed my cash straight down the toilet with their dirty rags.
