RCS nightmare

<p>On September last year I complained on hellopeter.com about RCS hounding me to make a payment on an account which was paid up in 2013. They promptly contacted me and sent me and their attorney a paid up letter. I thought the matter was sorted out...that is, until this morning (11 June 2016)when I received a call from their debt collectors. </p> <p>I, for the life of me, can't find the paid up letter to send to their debt collectors. But is it my responsibility to inform their debt collectors of paid up accounts? I think this is incompetence at its worst. </p> <p>Will this nightmare with RSC ever end??</p>
