Not sure who this is.. Anyone know?

A dinner time call from someone with an accent, who requests you to verify information that is listed in all types of indices.  Asking questions, but refusing to state the purpose of their call.  Indicated they were calling from ICC.  OTHER CALLERS CAN BE HEARD IN THE BACKGROUND, INDICATING THEY ARE CALLING FROM PURCHASED OR OTHERWISE ACQUIRED LISTS.  DIDNT REMAIN ON THE PHONE LONG ENOUGH TO OBTAIN ADDITIONAL INFO.

I am on the do not call lists and still get calls early morning, dinner time, and evenings.  Caller will not state the purpose of the call and requests verification of who you are.  Have stated that they are not to call again if they cannot identify themselves.  If collector, then state that!  Very annoying and inconsiderate!  Person calls, asks you to hold on and transfers you to another who then does not tell you the purpose of the call!  No less than 10 times.

This is a collection agency tied to medical.
You must of had some medical attention at one time and they need payment.
