Quality of the office cleaning that they provide is poor, many nights the only visible sign that they've been in our building is empty trash cans. They provide a list of cleaning they will preform each night and much of the list is unaccomplished in the morning. It is rare to come in and find things have really been cleaned. They have regularly left our building unlocked after cleaning, it happened again this week.. Each time they promise that it will never happen again. They are unresponsive to customer complaints.
