Urban Upkeep

I purchased this window cleaning service on groupon. It is easily the worst and most unprofessional service I have ever received. They cancelled the day before my cleaning on 3 separate occasions and then on the 4th time, they assured me they would be there. I waited an entire day, but they did not show up. No phone call, email, nothing. I tried to contact the company, but they would not return my phone calls or emails. Do not ever use this company.
