Remedial Request

I received a request for a remedial about three weeks ago. I followed through on that request and had the remedial completed. Now the place that i received my remedial is trying to charge me for the cost of the screening. I thought that these appointments were all paid for and that we must not give out insurance cards or anything like that.
So my question is: Should I first call the place where I received the remedial or call Concorde and tell them that I was miss-charged for this request...
