Hi Mujahed,
That page is part of a wiki system, and any registered user (including you) can edit it.
You should be able to see an edit link at the top of the screen (circled in red in my screenshot attached).
Rather than simply deleting the link, perhaps you might consider adding a link back to this topic. Perhaps something like "refer to this Coderanch topic for problems noted with this product". That way anyone who is reading through that wiki page can come here and find all the issues that you noted, including the valuable advice regarding the 7 days return policy.
Thanks for helping make this site better!
