Just to be VERY CLEAR, the company sending out harrassing phone calls is IQOR http://www.iqor.com/ not ICORE. iQor made up that crap name so no one could find them and would look under other names.
iQor is an international collection agency that has been annoying people around the world for years. iCore is a 100% legitimate part of the Alberta government that gives out grants to graduate students and professors.
Please stop confusing the two. iQor is trying to confuse you, so don't fall for it.
If someone calls you and claims to be from "iQor Canada, " know that they are LYING TO YOU. They are NOT in Canada.
Ask them how the weather is, because they'll never answer "snowy."
