Netflix is losing its mind

Ok, so I think Netflix is losing its mind. 3 days ago, I got a movie 1 day earlier than they said I would; this is fine and it happens fairly regularly. As per usual, I returned it the next day because I was done with it and didn't give it a second thought. Until today that is... Today I received the other two movies that were supposed to have arrived the same day as the previous one; they came 2 days late which is ALSO not unusual for Netflix. The odd part is that they were not alone; they had brought a friend. I was not aware that Netflix had received the previous movie that I had returned and, as I am on the 3/month plan, I should not have received another movie until they did in fact get the returned one. The odder part is that this third movie, this innocuous buddy to the first two, this hanger-on, is the very same movie I just returned. Now, some of you may say, "well the post office probably made a mistake and returned the movie to you." Those of you who are familiar with the Netflix system will understand how easy it is to tell that this is not the case; the packaging that the DVD is in is different. In all likelihood, they will receive the first version of this movie that I returned and post it to my account as 'Returned' thus putting me in a position to have a free movie. Being the law-abiding citizen that I am, I will obviously return this copy as well but the situation remains: Netflix is losing its mind.
