Samsung S20 Sprint SM-G981u unlock problem

ok so initial issue was that on first attempt it said it was unlocked but still was getting invalid sim but box still took 20 credits, i then retried the unlock operation again and the phone eventually got unlocked and picked up signal but took another 20 credit.

A few hours after returning phone to customer phone goes back to invalid sim again. is this solution a permanent solution cause ive wasted 40 credits now Along with no solution. BTW i am usng the lasted version of the software.

below is the log of both unlocking attempts, do note that i started Along with 42 credirs and ended Along with 2 and i still have a locked phone. PLEASE REVERSE MY CRDITS BACK TO ME ASAP and advise me how i can get a permanent unock for this phone from z3x also is there a telegram or whatsapp support we can communicate Along with z3x on directly so we can have issues like this resolved quicker?
