We were unable to find out where Mega Ebook or where the owners are located. The information is not on their website, and they are hiding their domain name information by using a third-party service. We do not recommend purchasing from websites that hide their locations. But, that doesn't necessarily mean the websites are fraudulent, it just makes them suspicious. And, when you are operating an e-commerce website where online users enter their personal and financial information, it is important that the website discloses all possible information about itself.

Online users who have used their credit card information on the fraudulent website are asked to contact their banks for help. Their banks should investigate, cancel the fraudulent transactions and refund their money.
The fraudulent website also hosts another scam, where it claims visitors can get a new iPhone X for only $1. But, this is just another method used by the scammers to trick potential victims into using their credit cards on the fraudulent website. If potential victims fall for the scam, their credit cards will be continuously charged randomly for different amounts.
