Pathetic Pathcare customer service!

Pathetic customer service! I received an account in July last year from Cheslyn Marks and responded with my medical insurance details. I did not receive any response so I thought the account was settled. I do not send my insurance any other bills for payment all the other medical institutions deal directly with them. Now 7 month later I am about to be blacklisted with Vericred debt collection agency AND I am liable for the full amount owed plus collection fees. The insurance company will not pay the account after 3 months (I find this out today) It takes 2 minutes to respond to an email and inform your clients they must deal with their health insurance directly. Now the bread and butter is taken of my table from this companies incompetency! I am NOT A HAPPY CUSTOMER.
