S8+ will not carrier unlock

I have an art galaxy s8+ i purchased from a third party outright.


I requested a carrier unlock code from att and was approved.


When I input the code on the carrier unlock prompt it tells me my unlock code is invalid .

I requested the unlock code a second time just to ensure I had the correct code . The request was approved once again and the exact same unlock code was provided so I am assuming the code is correct .


I have tried using a different sim as well as accessing the unlock prompt directly using the phone dialer. It continually tells me that my unlock code is not correct. 


I have verified that the imie number matches exactly on my unlock request. 


What is my next coarse of action?
