can't unlock an S9 +

[techmania97]

hello, I have 2 problems
I bought credits, I launched the unlocking and it disconnected the phone and the operation was stopped without unlocking the phone but like even keeping the money and when I restart the unlocking, he wants me to add more credits.
the 2nd is when I get to the "activated diagnostic stage by doing * # 0808 # it can't find the phone and I get stuck at this level.
