How can i un-cancel a cancellation; i sent a parcel to mexico and the buyer said via a message that mexico post had delivered it somewhere but they didnt know where; i cancelled the sale so i could claim my loss from royal mail and The buyer wouldn't be out of pocket; day later the buyer messaged me saying the parcel had arrived, i dont knowhow to deal with this as i dont have the goods any more and have lost out by doing something for the buyer; does anyone know how to un-cancel a cancellation
