[member=4149]Christine2[/member] With William Hill you can't always 'see' the free bets, but once you put a selection into your bet slip then there's a little drop-down box where you can select to put the bet on using your free bet. Try that first. You don't have to actually place a bet, but it's just a way to check if your free bet is there. Then you can delete/remove your selection from your bet slip. Also, try logging out and back in again.
William Hill have got me before where they've sent me an email with an offer, I've done it according to the T&Cs and then it turns out that I should have opted in...even though the email didn't say that I needed to opt in, but if you click on the banner in the email it might take you to an 'opt in' page. What I would do is to go onto Live Chat and say something like, "You sent me an offer but I'm not sure how to find it" and just play the 'confused new account holder' sort of role. They can advise you...and if you should have opted in then they might waive it this one time and credit them for you manually.
