Solomon threatens clients

I have signed up for debt review with New Debt Plan and recently a multiple amount of my debts have not been paid. I logged a complaint as an irate client and Solomon who is rude and unprofessional has responded threatening to ignore my Emails. I have requested feedback yet he gives bland rude answers just telling me that if I am irate he will ignore me and has never provided feedback. What kind of company threatens to ignore a client??? I will make it a point to have this escalated as far as I can because 1. They are not doing their job and 2. Solomons service is the worst I have come across in my life!
