The Bitcoin Cash hard fork has resulted in creating multiple chains. However, as they are not secured by replay protection technologies, there is a chance of double-spending affecting both chains (BCH/BSV or BCH/BCHA). It means that transactions made with one of these coins may be replicated for the other.
In such a case, please contact our support team at [email protected]. We will do our best to refund you within 24 hours. Still, we have to warn you that in some extremely rare circumstances there may be no chance of getting the funds back. The best way to avoid it is to split your coins: please make sure you did it before arranging a transaction.
