I've been using this service for almost a year now, starting in April 2023. We've gone through a lot of moments, including DDoS attacks from competitors who promote their similar software for invites. This shows that Tgninja has become a real irritant for some software vendors. The service works and performs its tasks excellently. As for the technical support, it's just wonderful: the owner of the service is present in the TG chat for almost 10-12 hours a day and personally addresses customer issues. Unfortunately, there are some unreasonable people among the chat subscribers who, without understanding the capabilities of the service, start making unfounded complaints. Or they could be competitors sent specifically to tarnish Tgninja's reputation. I see that one of them has already appeared here. Don't believe them, come and subscribe... They offer 5 days of free usage, and the friendly tech support and large group of Tgninja users are always ready to help. It's better to test the service yourself than to rely on someone else's reviews.
