On XXXX Tue XXXX I was telephoned by PORTFOLIORECOV XXXX. 

The caller refused to identify the purported creditor, the account, or the amount. I therefore have no way of knowing whether this matter concerns me. It could well be a scam. 

The caller hung up after I refused to continue the conversation in the absence of validating information. 

This was my first contact with this party ; by the FDCPA they must contact my in writing with a Validation Letter within five ( 5 ) days.
