Hi Juanjo99,
Thank you for posting in our community and welcome :).
It should be possible to log in to your transaction history and to go back to that date. Please make sure that you adjust both the dates so that you do not select a timeframe more than a year. When you adjust this you should be able to review that transaction from April 2011. If you are still having troubles you can always contact us and we will have a look for you :).
