Issue with canceling my contract

An agent named Nancy Sekano informed me that the cancellation takes 30 days, she's put me on hold for the last 30 MINUTES. I'm currently on a month-to-month contract. According to one of your stores, it takes 24-72 Hrs. I was also informed by an agent that the cancellation will be effective when the port kicks. I requested a port on 11 May 2023, but it failed and no one informed me. Your website also states up to 20 days. It seems like no one is consistent with the process. I want the contract to be canceled immediately, please. You are holding me hostage to your network. I've moved over to another network but cannot use my number.
