Android Studio Gives Google Pay Error, How Do I Solve It?

Question

I want integrate Google Pay in my app. Everything works perfectly fine until the payment comes. I am getting an error saying "You have exceeded the maximum transaction amount set by your bank" and I can't make payments, even though I have not made any transaction with Google Pay in last few days it still gives me the same error. Here is my code
