I used 1440 Concierge to make some phone calls to my delinquent accounts and they did an excellent job. They were very professional and considerate to my clients and called me when they were beginning to work on my project and let me know when they finished. After they finished, they emailed me an excel spreadsheet with each client's response to the call and the action the client intended to make in getting the bill paid. It was extremely helpful and saved me 3 hours! I will definitely be using them again!
