rephen law is a phony Yes or No

I was called from Rephen law in New City, NY asking for 3600.00 for a bounced check that I never wrote. They told me that the check number was 9751 but could not idenify the bank and we are not up to check 9751. when I asked for the bank name or details, invoice ar any information they could not give that to me. the person I spoke with was Elisibeth Parker and her direct line number is 845-678-1265. It seems odd that a law firm would not have back up information on hand and be willing to share that with you. When I called the law firm they claim to be a colllection firm but are they? In any case i am sending a letter to both the attorney general's office and the NYS law board.
