Returning Equipment

I moved in June, tried to return equipment to Videotron store, they told me videotron would send me details on how to return.  Never received any information, so I called.  They told me they would send me an email on how to return.  They never did.  However i kkeep getting messages on my answering machine from videotron telling me to return my equipment, with no instructions.  They only told me to come look on this forum and i cannot get any answers.
