You may want to send this question to Customer Support in a more direct manner, although I have seen them respond to questions on here as well... You might want to scramble looking for it or see if you let any friends borrow it.
This question may be better for the customer support area so that you may notify GameFly employees in a more direct manner. However the best answer I may provide you with is to make sure that the last game you returned was received before the date of your scheduled payment.
If you've lost the sleeve to a game, please do the following:
Write your first name, last name, and e-mail login on a sheet of paper, along with the title of the game you're returning.
Place the sheet of paper into the pre-paid shipping envelope with the game.
Mail the game back to GameFly as usual. Once we receive the game, we will create a new sleeve and then return the game which will delay the processing of your return.
In the future, please hang onto the game sleeve to avoid any return delays.
If you've lost the pre-paid shipping envelope, no problem! We will be more than happy to send you a replacement. All you need to do is:
Go to Report A Shipping Problem
Select the specific game you need a replacement for and the option I lost the game's shipping envelope.
In the upper right part of the page you will see "GameQ". Click that and the page will load with your Game q. Plot twists aside, if you scroll down above your game q will be a separate section titled "Games I Have Out" where it will tell you which games have been shipped. Keep in mind that there are only a certain number of any given game and if there is none available, you will have to wait your turn, or the highest game on your queue will be shipped as soon as possible.
In your upper right corner of every gamefly.com page you will see a name to the left of "Facebook" "Twitter" images and then "Support. This should most likely be the name you entered for your account.
Hover your mouse over it and a menu will drop down, click My Account and wait for the page to load.
When it loads, look to the far left of the screen, scrolling down until you see in bold letters "Account Activity". The fourth link below that says "Rental History". Click the link and a page will load with information of the dates games were sent and received upon return, as well as the location of the Shipping Center and their current status.
You may keep a game out until you grow tired of it and decide to ship it back , however pending on your plan you will not receive another game until the video game you currently have is returned and received by your nearest Game Fly building. With the holidays expect delays in the postal service.
