A lot of these "never heard of" Rogers Cable / Home Phone accounts are popping up these days for good reasons: they did not use to appear on the credit bureau (and/or other agencies did not report them), while iQor certainly can and does. Which is why many find Rogers debts they incurred in 2005, 2006, 2007 and have no clear recollection of, having not heard of them ever since.
Also possible is that you had an account with Sprint, and it got merged in when Rogers bought them off.
Good news: iQor agents are at a full liberty to settle for as low as 50% on all such accounts. If offered to pay NOW they will almost always accept... if they don't, they're stupid: call back an hour later and speak with someone else. :)
If you need any details I can receive PMs with file or account numbers (or even names, if it comes to that) to find out more info for you, including balance and best settlement possible.
