Cleveland Clinic has been harassing me about a fraudulent debt from 2000. I paid over 30, 000 for in vitro fertilization and I specifically asked about the cryopreservation costs for my remaining eggs. I was told there was no cost. 4 or 5 years later they sent me a bill. I disputed it then I've disputed it ever since, and asked for proof of responsibility. They never sent anything but have continued to bill me and continued to report it negatively against my credit bureau. I am getting threatening letters that they will send my account to collections and have yet to see any documented proof of my liability.
