Cancel Gamefly Game Rental.

My Name is Cristian Diaz. I have been trying to cancel my game rental service for the past few months. This last charge from Gamefly overdrew my bank account. I had made contact online which indicaed my request to Cancel was accepted. Now, I find it is still in place. What do I have to do to CANCEL my Service? If you are not able to Help Me I will instruct my Bank to No longer except your request for another monthly payment. Your Service should not be that difficult to Cancel. If I or my friends new how difficult it would be to Cancel, we all would end up filing complaings with the Better Business Bureau. Please contact me Immediately Cristian Diaz
