I understand that you may have had problems, but we all have to fulfill our obligations. You held a person's money without providing relevant service in return. Not just for a short period of time, but for a long period of time (i.e. 2+ months). Whatever the circumstances are, you are responsible for your actions, and therefore the consequences that forego it.
edit: Well OP decided to avoid his MP ban by participating in the MP on his alternate account. Shame.
