I got failed in assignment which i took from them. Why i ask them for an explanation, i don't even a get a call or proper email. I did raised for a refund, they don't even respond to your phones/email. One of the worst service i have seen in my life. Please don't trust them, they keep some crap in their website (Money Back Guarantee, Unlimited Revisions) Don't trust them, even after revision you won't see any improvement. Worst writers i have seen.
