There are two ways to get unbanned, unless there is a way that I am not aware of. The first way, you can submit a punishment dispute
here. However, if it has been two months since this punishment has happened, this option is not available, and your punishment is considered outdated. If this is the case, then you will have to buy your way out of it. I do not suggest using this method if your ban isn't permanent. For example, a day, or a week. If this is the case, then I would suggest waiting it out. If your ban
is permanent, then you need to pay real money to get out of the mute. It starts at $20 the first time you buy your way out of a permanent ban, but the next time you get a permanent ban and pay to get out, you have to pay $40, and after that, you can't buy an unban anymore. To buy an unban, click

Hope this helps.
