On Friday, January 25, I received an automated call claiming that I had been billed in December for a date of service in early Novermber and that the due date was Jan. 25. I have NEVER received a bill from them -- neither in electronic form nor via the U.S. mail. I called and spoke with a representative of theirs. After some digging, she realized that, although the system showed that I had been billed via email in December, my email address was not even in the system! I cannot pay a bill that I do not have. The person I spoke with said that she would email me electronic copies of all the invoices, just this one time, and the bills would come via U.S. mail thereafter. To date I have not received that email nor any statement via U.S. mail. It makes me wonder whether CareCentrix is doing this intentionally as part of some fraudulent practice by which they wrongfully transfer accounts to a collection agency.
