bocoz you are using Card of stupid government banks one fcuking example SBI they have lots of restrictions .... and when you try to contact the customer care of GOv banks .. they will laugh at you and tell.. you are mad .. bla bla and bla .. they will tell what the fcuk is google checkout ?
also they will hardly listen your issue ..
even the CC of Gov banks are rejected .. by PayPal and GOogle checkouts .. lol


I suggest use the cards of private banks .bcoz they have lifted restrictions and have freedom to purchase online and friendly customer service to help you every-time
my debit cards works like charm in PayPal and google chckout
