SOS Maintenance contracted AJs Refrigeration LLC for a boston Market walkin cooler repair in Denver Colorado for $20, 400 and agreed to pay net 15 We are at almost 60 days and get nothing but the run around and are now filing a lien and taking legal action. The original account manager supposedly no longer works there, I googled them prior to taking the job but evidently there was not enough bad press for me to pick that up. I am seeking to remedy that situation. Don't do work for these folks unless they pay you in advance. Looks like a scam to me.
