The Paper Experts, a scam?
I went to paper experts today, thinking that it would be a 'good' site, however, the service was going to be about $299.5, this is how I calculated
26.95/pg, ten page, so that is exactly $269.9
Furthermore, delivery options include by email, US$2/pg (I know it's a ripoff)
and a Receive article Sources $0 (it should be $20, and $10 PER article, however, I provided all the notes, because I don't really have the time to write my essay).
So that is $269.9+20, or $269.9+30, which equals to:
$289.9, or $299.9
However, when they calculated it, it became
Price: US$319.50
Extra: US$ 30.00
Adjustment Fee: US$80.00
which finally became:
$429.50, and they charged it instantly when I called my credit card company
Without having me to sign the paperwork that they sent to me, the receipt and things like that, furthermore, because they said that they are a Canadian company, the receipt said that it was: $536.88 (CAN) I don't even know if they would charge US or CAN.
Furthermore, they sent a E-Mail of *****62 purchase agreement, while it should be *****60 purchase agreement.
Therefore, is this Fraud? By giving me a price of $429.50 or $536.88, when I calculated it to be $289.0 or $299.0
I mean, the Email thing is ridiculous, If I had a desktop, Email the copy, takes 10 seconds
I have a voltage of 120V on my outlet, PC usually takes about 1.1A or 1.3A, estimation
120*1.3A=156W, ok
If I had a Frypan of 1200W and used for about 10 hours, it would only cost $2.07 electricity, imagine how many Frypan I could use at the same time for 10 hours and would cost $20 dollars, about 10 Frypans.
Better not waste my time on them and finish the paper by myself, sad, how can a history, paper about communism cost $450?
P.S: Sorry about my english, that's why I need to find Essay Services, sorry if I broke the rule
