title: In-App-Purchase consumable product managment
body: <p>In My application I am using consumable in-app-purchase for SMS credit and managing this credit from my server. Application send me the receipt of transaction on server and I verify on server.</p>
  
  <p>But in one of transaction receipt is not received to server but customer money is deducted. So there is any way to verify the purchase on iTunes. So I can check and add balance to client account. </p>
