The customer service is excellent! I have been working with them for over a year now and they are always willing to help me out when I need it. They also offer free training classes and are very knowledgeable about their products. There really isn't anything I dislike about this company. They are great people to work with and they make sure you are satisfied before they move on to the next client. We use Waste & Recycling One for our monthly trash pick up. It has made the process much easier than having to go through multiple companies each month.
