Unfortunately, your domain is likely to work here, please see if you can get a refund from your registrar or buy a new domain from Namesilo, etc. Reason:
When you try to point your domain to InfinityFree’s nameservers (ns1.infinityfree.com and ns2.infinityfree.com ), your registrar might refuse the change with error messages like:
DNS Query Refused
ERROR: Answer must be authoritative
The name server is not responsible for this domain
Domain is not activated in the nameservers
