Amazon Pay Vouchers Via SBI Cashback

The million dollar question -

What are the ways left to get amazon pay vouchers via SBI Cashback CC with 5% discount?

• Tried Park+, got a 2k gc and then it says 'come back tomorrow' lol.
• Amazon Pay voucher via Amazon doesn't work anymore?
• I heard magicpic hack doesn't work anymore. Please confirm.
• Any other methods?

Thanks in advance fellow redditors.
