From our point of view, screenshots of dialogs with our clients will be the strongest argument because they are hard to fake. On the screenshots you can see a part of the correspondence from WhatsApp where you can see that the person really sent money and received what he paid for. Below are the screenshots of these correspondences (there are over 500 of them in total).
In addition, we have been selling our Mortal Kombat services on the American marketplace for over 4 years. You can see it in our profile: https://www.epicnpc.com/members/pandastore.1085459/ Also there is a tab “feedbacks” where you can also see reviews which are more than 200.
If you still have any doubts or questions you can ask us personally and we will provide you with more evidence
