I represent a client and am doing work for her on her finances, credit, and debts. 
I received a call from someone saying that he was a friend of my client and wanted to know what services I provide. He mentioned my clients name and asked if I knew her. I confirmed I did. I explained what services I provide. He then said he was unsure if he could work with me. I asked who he was and he did say he was with Van Ru Credit Corp. but would tell me no more. I asked " are you debt collector '', he said " he could not answer that ''. I asked " are you attempting to collect a debt '', he replied " he could not say ''. The call was then terminated.
