My opinion about this accommodation is very bad.
I do not recommend the service of this type of reseller at all.
Hide your DNS with CloudFlare so we...
can not track where you buy the services.
Clearly it does not have its own servers.
In addition to the malfunction, you do not want to make a refund.
If there is someone who does not believe in my word. I pay the accommodation to do the test with the condition that, after testing the service, leave your opinion on this website.
Just see this example of DNS usage.
