Guys how to add VP if u dont have paypal or credit card ? where is upi option ?

Last I checked there was an option to pay that way you had to fill in your details and then it re-directed to third party for payment.
But honestly easiest way is debit card option like visa or MasterCard just enable international payment and it should be smooth
If these options don't work for you and you are willing to shell a bit extra you can buy VP points card of codashop and such websites and redeem your code in game store

Just purchase from razer gold webpage its more authentic and cheaper than in-game prices
