Hey! Yes had similar issues and sent them a message at the time when it didn't work. This is all I got back from them, quite a while back.
"We note from our records that you input a fill or kill order to invest £X into William Hill limited at 60p. This means the service will attempt to fill your order at 60p or better. If this is not possible then the order is 'killed'. Fill or kill orders are handled in turn, the time at which your order is attempted is dependent on the volumes of orders we have received. If you wish to deal at a specific point it is necessary to deal online when the market is open. In this case when we came to place your trade we were unable to fill your order at your limit price, so it was 'killed' and a confirmation email was issued to you".
Problem was, as it didn't work.. it was still active and then didn't let me buy it normally either.. by that point had gone up! Anyway, I try not to use the fill / kill anymore, just try my luck buying normally first thing. Good luck!!
