If you are unsatisfied with your deal or order, you can open a dispute to try and solve any issues you have directly with the other party.
Opening a dispute will require you to stake some MTH tokens. The other party will have to do the same; we will also temporarily reduce their reputation score. If they fail to solve your dispute, they will not regain their lost reputation, and you will receive all of the staked tokens.
To open a dispute, go to the deals page, select the deal you are having problems with, and tap "Open dispute".
