Alleged debt from 2018 sent directly to Collections General Credit Services

Hi, see my previous post.  I was reassured by Telus this was solved a couple of months ago.  Like you, I am now being harassed by collection agency.  I have told them to cease and desist especially after a second reassurance by Telus on the phone today and informing the collection agency in writing.  If it continues I will be making a complaint to the CRTC and copy the Minister responsible.  What a glorious waste of my time for bill that does not exist as stated by Telus-twice.  I am also researching to see if any other federal ministries are still dealing with unfair trade practices and will proceed accordingly.  All that has to happen is that Telus collections contact the collection agencies involved(two levels) and inform them that the debt does not exist.  To date after several months, they appear to be negligent in doing so.   If I see a negative submission which affects my credit due to a non existent debt and associated negilgence then I will proceed further.
