Your domain is not pointing to the right nameservers, or is expired! If the reason was the first one, please change the nameservers to ns1.byet.org and ns2.byet.org from Freenom’s nameservers management panel for your domain; if that’s the latter, register it again with those nameservers.
I’m sure that someone can help you, but that someone is not on this forum. If Freenom has suspended your domain for fraud, then only Freenom can tell you why your account was suspended or tell you if or how you can get it back. Please remember: this is the InfinityFree, not Freenom, forum. We can help you with your InfinityFree hosting service, not with whatever third party services you use to build your website.
