I have not been a koodo user for well over a year, but I have recently been contacted by a collection agency asking for over $500. I was under the impression my account was closed because I went to a koodo booth at a local mall, provided them with my account info and had asked for them to close my account. I logged onto my old self-serve account as my username and password was saved onto my laptop and it says I owe just under $500. Can koodo look at their records and recognize I have not used their services for the months they charged me for? This is effecting my credit greatly and I can't afford to pay for these services that I didn't even use.
