There is a differnet between "after work approved" and 'after completion" , I think it is obivious for everyone , you did not asked for more details and we were very cautions in choosing our words , we have received more than 10 scam translations only for the same whitepaper you worked on , how can you expect us to pay for something not approved by a native speaker , ? (I am not accusing your work quality here)
You can search for the legal meaning of word "approved",
Another time , for everyone who claim a scam , for the moderators they gave us Red flag , we are here to solve the problem,,,
