Then, what you need to do is simply logging into your PayPal account, start a complaint process in the account for not receiving your item. This option was in the resolution center of your account before, I don't know where it is now but it's somewhere there. You write down what's your issue, submit the complaint, and very likely PayPal will give the money back. Provided 4 months is still inside the complaint time limit after the purchase.
This is the usual way you can get your money back at Fansofcongo. As I remember it was created from Villageafro, where your case was usual, and one could get the money back by submitting a PayPal complaint. You could always order something there in the past worry free, because if the order was not processed you could go this way if they were silent to get the money back.
