Unable to Use My Phone Number on Main Discord Account Due to Old Account Issue

I created a second Discord account to mirror phone games, and I added my phone number to that account. Later, when I tried to add my phone number to my main account, I was reminded that the number was already in use. To fix this, I deleted the second account with the phone number, as I wasn’t using it. However, the problem persisted, and despite repeatedly reaching out to Discord’s support system, I kept receiving responses from an unhelpful AI that didn’t understand my issue.

I just want to resolve this phone number issue once and for all, so I can link my number to my main account. It's been incredibly frustrating dealing with this, and I need a proper solution urgently.
