after creating new account, i didnt’t get free credits 
If you created another account with the same email/phone number, you will not get any free credits.
no, i created account with different mail and different device but still no free credits
Are you sure you used a different phone number? You can still use different devices with the same phone number when you register.
yes i used everything different
Sorry, can you update it, for models you can no longer use Ada, Babbage, Curie and Davinci. Is there a newer model, because I have used the four models above but they still don’t work and have errors.
