Hi, If you're in india then you'll get chatgpt go for 1 year, to claim it first make sure your chatgpt app is up to date and then if you're using Android go to settings and clear your cache and data for chatgpt app, after that login and you'll see an option to apply for chatgpt go for a year, you can use upi to set-up autopay and it'll charge you 2 rs and then it will credit you back that 2 rs, once you get your 2 rs back you can cancel the autopay, it won't invalidate your subscription of chatgpt go, after this is done you need to go to your settings again and clear cache and data for chatgpt app, after that login and you'll see that you have chatgpt go subscription active.
