Hello Andrey,

I have tested the API and it seems to be working well. Please check the screen-recorded video for reference: ” https://excellentnumbers.com/temp_vid/Screencast%20from%202025-11-24%2014-12-10.mp4 ” .
If there is any other issue, please ask the admin/customer to be specific about it. I am not sure why they are facing this problem. The number they mentioned as out of stock or unavailable is not on the site—I have already verified that as well.

I am currently checking the refund issue. I placed an order of 3 numbers and applied for a refund, and I received the refund amount email. However, I did not find any option to refund a specific number from the order list. I am still checking and reconfirming this issue on my side.
