Welcome to the community!
If you would like to verify you have the 1000 International minutes on your account, your best option would be to contact customer service. This is the community forum and not intended as a venue for customer services. They can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
You should note that those 1000 International minutes are only to certain Countries. You can find the included Countries here.
Hope this helps 😀
