Money making or service provider

I am once again very and extremely disappointed in Polmed services. Both with the customer care and how they handle the billing and paying of service providers. Accounts get handed over to collecting departments without our knowledge of polmed short payments and yet when we call the customer center, we are told we are just liable because of the disclaimer form we sign or do not sign. Call center agents are misinformed, rude and very ***********. She even hung up while I was talking to her. I would like this matter resolved by polmed asap.
