Seems like forever!!

I mistakenly blacklisted the wrong IPhone due to my daughters having each other’s phone boxes however I called the customer care line and they sent me the form I needed to submit. On the form it said the turn over time is 24 hours I submitted on the 7th of July 2022 and the date today is the 13th July 2022 no one has contacted me on the progress of the unblacklisting of the phone. How do I go about unblacklisting it because my daughter needs her phone.
