There is the guarantee of free revisions. As they describe it on the website, users with complaints about the paper quality should contact the department responsible for amendments. There are contact details for each dedicated department and the names of every person in charge.
If you need a revision, you should apply within 7 days after the delivery and describe all the problems defined in detail. The company promises to respond as quickly as possible. Unfortunately, it does not provide any other information about the revision service – we failed to find any details about the number of allowed free revisions or terms.
