Contract cancelled

I cancelled the contract in April 2024 due to the agent not fully disclosing information and added fees when taking up the OnAir Explorer package. I requested for the account to be closed and ITC information to be updated. It's been 5 months since that request was sent till today the account is not closed and my credit profile it reflects as being in arrears. I called OnAir and today i am being told of a 6 months backlog what ******* is that. When you guys are collecting your items that didn't take 6 months now when you need to close accounts it takes 6 months. I need for my profile to be updated on ITC as soon as possible.
