These companies, such as Omega XL, who make it impossible to get the refunds they guarantee should be stopped.One way to start to force them to do what they said they would do is to flood their social media sites.
Most companies have several social media sites. For example, go to Omega XL's Facebook page and write your experience. If they don't allow you to post on their wall, write your experience in their comments section.
Maybe even write it in the comments in several of their posts.You may find that they will contact you to try to resolve your issue.
