Looks like you were banned for scamming: https://www.mpgh.net/forum/showthread.php?t=1165582
Last time you came back you were told to hold a giveaway for the amount scammed: https://www.mpgh.net/forum/showthread.php?t=1435518
I will mention @FatEmoLLaMa to give him an opportunity to be refunded, but he hasn't been active in over a year so you will most likely need to complete a giveaway.
