AWFUL service, these people are just not capable of writing anything at university level, if you need an assignment at school level maybe and just maybe they would be capable of helping you.
DO NOT waste your money with this company learn from my mistake! To understand how rogue this company is, you need very carefully read their policy and you will understand what am I talking about. The main point is, that this company offers the service, but cannot guarantee for the provided service! I think, only this is enough to avoid any business with them.
So please, read their policy very carefully and be very CRITICAL what you read about them elsewhere! Do not think that the grass on other side is greener.
