One of the brokers I trade with cancelled all of my trades citing a 'manifest error'. I shall be taking it up with the FCA as they are regulated.
Basically if this happens it shows that you were probably dealing with a bucket shop that was the counter party to the trade and they aren't prepared to lose the money.
Depending on where the broker is located I would look into reporting them to the authorities.
