I'm in the process of solving the situation with the customer. Therefore, I see no need why you should dwell on a non-issue :)
I don't think this was the point being made. You are referring to your client as "lazy." Based on the fact that our business only exists because students do not want to complete their own work or cannot do so for some reason, such as poor written English or time constraints, youd be well advised to avoid making statements like that, irrespective of having issues with the client or the work involved. This is just unprofessional and insulting to both your actual and potential clients, and also to other writers that see your "lazy" students as their valuable, primary source of income. Good luck trying to garner orders with such a poor attitude.
