Jzanus Ltd. Debt collection department,

Medical Disclosure verification of debt Not given enough info to verify debt New York

Threatening to report to credit agency amount in dispute. I have asked the the debt collection agency what the amount due is for and they tell me to call the hospital. Since they have no billing info there is nothing I can call the hospital about. Spoke to Supervisor - -, on -/-/15 who said he would contact hospital and find out what the amount his office is billing is for and call me back on Monday -/-/2015. A week later and he still has not called. I tried to call him today and was unsuccessful in getting him to the phone.
