I ordered the completion of the latest…

I ordered the completion of the latest Genshin Impact Chapters due to that i had no time to do it myself. The Booster i got assigent, jupa6515, was very friendly and kind. They showed a lot of understandment for the Time i wanted to have the completion done wich was also a great point for them. I asked them if they would check in with me every other hour so i know where they're at. That turned out to be not nessecary and any of my worries were also denied by them. So overall i defently can say i was very satisfied with the service and the Result. I would order it again with the same booster!
