Do not waste your time and money with those unprofessional people. Their level of academic English is substandard.
I had to get rid off most of their corrections and do it again.
They were very bad in following my instructions, which made my document even worse!
I've asked them to refund at least a part of the payment, they ignored my email and messages which you would expect from unprofessional and not honest people.
STAY AWAY AND SAVE YOUR MONEY AND TIME!
