Because I didn't have time to find another one, and I haven't though "need a little more time" means 20 hours and more.

I haven't slept in the 20 hours, and keep trying to contact him in last 10 hours, but NO response; then contact to the support, NO response.

Because they have provided previous services, so I did NOT say they are scammers, I just complain the deal.

The good news is, the support has replied right now, said my order will be finished shortly.

Is it possible for me to request the different prices between 1-day and 2-day order? Has any precedent?

I just worry that my research paper will not be delivered on time and I lose points because of that. Makes sense?

Actually, I like reading your quarrel online, no matter who are right or wrong, it makes me learn native speaking soon!
In our online language, we call it "mouth cannon", or "academic" translation as "oral artillery"

How did you say that in native speaking?

By the way, my order hasn't been finished yet, sigh..........

I have uploaded the screenshot of my order to let you know the truth (hope the picasa works).
