i finally tried to purchase my first app, beautiful widgets, i have a mastercard debit card and the item says purchased but when I click install it says download unsuccessful and I received 2 emails one from google with the checkout receipt and then another from the developer's saying card was declined for either 1) not enough funds (which isn't the problem) or 2) its been put on hold for fraud protection, my bank account is showing the purchase coming thru and like i said it says purchased in my market downloads but won't install, I've emailed the dev no response, what can I do?
