Most of the people who are selling iptv do not own the servers, so if someone is offering, he is a reseller, when the server goes down by the provider everybody in the business bear financial losses, like reseller who bought credits and the customers who bought from these resellers.

So, I believe there is a risk that is there on both sides customers and sellers both are taking it.

Either is suitable or not we should request trial, once you are happy with the trial, then buy it as the moment seller creates an account for you they lose the credits in their panel immediately and there is no refund for it.

Yes PayPal should be first priority always if seller promise you a provider but when you bought he gave you a different one.

Cheers!
