To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Despite entering my credit card number saved to my Amazon account to verify it was me making the order my order for this item got cancelled and my Amazon account got locked. Dont bother with this just use your card directly on Google Play, it will be faster and less hassle.
