failure to do follow up admin and proper staff training by Miway

I have used my way for a while and was and still am very happy with the service and cost how ever 2 years back I had to discontinue my account with them and despite this they have kept the amount I was paying on my credit profile not as you ma know it then looks like I am paying that account as well as the new one they have loaded on my Profile. I have called them and held on forever then requested a call back after having been on hold for 40+ min then after a week I get a call from the most clueless of their consultant that then tells me that my account that was discontinued 2years ago was only canceled in April, now my question to her was then who had still been paying it if according to my knowledge and email communication I had cancelled it 2years ago she then became dumbfounded. I asked her to send my call to the team that is responsible with this updates so I can have them advise why they have not removed the old account from my profile, She said she would do so but I have been waiting since. I am really not happy about this.
