app store

I was trying to download video star pro with my apple id and it kept saying payment method declined even though i had enough money. So i thought that maybe deleting and reinstalling the app would work but now whenever i try to download video star it forces me to add a payment method (i already have one) then it asks for my verification code and i put it and then it just is a whole loop of adding a payment method and putting my verification code. can anyone pls help me?
