Can we get more details? You were charged daily? Are you disputing each day? Certain days? Did you have your phone off? Cellular data on or off? Receive any clals? Etc

If you have been using your phone or have not taken the right measure in order to avoid being charged, what exactly do you want Koodo to do? Sure they could credit some days, but next time please take some time to read the following in order to avoid charges :
