I have to write my personal experience with the management of PaperHelp.org, this might be helpful to other users.
Yes I did have arguments with the writer and the customer service (Live chat) on the unaccomplished/incorrect paper work that I received after the deadline. However, I reached out to the management via email and explained to them what happened in an email. They've investigated the issue, and returned to me the next day with an apology and a refund option (90% refund of the payment to my card or 150% refund as a store credit for future use). Because I was so pleased with their care toward their customers I have chosen not to judge them on a one-time experience, I have asked for a store credit.
Some advises for those who want to deal with PaperHelp, please note that only if you have a strong case with evidences they will be very fair with you. They have a proper well-documented refund policy on their website. Please go through it carefully. Yes, refund is difficult to get, but some people might take advantage if tough rules were not there.
Your personal experience could be very different from others of course based on the writer that will handle your case. They are dealing with thousands of writers, in case you have any observations or dissatisfaction I believe they can assign another writer to you. You have three stages of review before the product is considered delivered. Once you receive the final product, you cannot argue for a refund as they have also paid the person who spent some time on your paper – not fair.
Be aware of delay, it happens in real life a lot, so they might ask you for an extension to the deadline. Do not expect perfection, not even in the paper you will receive. You will have to go through it by yourself and maybe add/adjust to what you see appropriate.
I have to say this; you might face a problem dealing with customer service operator (Live Chat) as I did. They were somewhat mean to me, however do not worry you can address this directly by sending an email to the management. They won't let you down.
Be realistic, patient, and accept imperfections.
