Need help verifying account is closed

I opened a new account and service plan. I spent some time on Xfinity chat trying to close the old account and plan. I was told that it was being closed and that I would receive a confirmation call a few minutes later. I did receive a call, but the service rep asked me why I had called in. I explained that Xfinity called me. The rep didn't know anything about the cancellation and said I may get another call. Can a moderator look into my accounts to make sure the older one gets closed out?
