how one can trust these website service.......
You are so obvious and your posts are terribly contradictory. Here you say that no service can be trusted and yet, in other posts (eg:
https://essayscam.org/forum/es/reliable-research-writing-services-capable-meeting-900/2/ you promote fastcustomessays.com. There is hardly a forum member here who does not understand that you are trying to slam all services in an effort to push potential customers to your site.
all r employing writers from India, Pakistan, Philpines and even from srilanks as against what they claim in their website
That you should blast writers from India is both hypocritical and insupportable. Do you know why? Because fast custom essays is an Indian company. The only thing wrong with that is your attempts to deceive potential customers into thinking otherwise by blasting Indian writers. BTW, a writer should only be assessed according to linguistic skills and academic qualifications. Any writer, whether from the east or west, a native or an ESL speaker, have to be evaluated according to the following:
1) do they have the necessary academic qualifications and have they provided proof of those qualifications?
2) is their written English flawless and completely devoid of any mistakes?
3) does their work come across as having been written by a cultured and educated native speaker?
With specific reference to fastcustomessays, any who order from it are taking a big chance. You know why? Because their webcopy is full of language mistakes. When a company which presents itself as a professional academic-writing services cannot manage to compose a good webcopy, that means customers should stay away.
Were you to have openly stated that you were an Indian company, rather than go out of your way to blast Indian writers, the only problem would have been your poor webcopy - easily correctable. However, you chose to deceive and that is difficult to correct.
