I emailed Warners (thanks Jan) and got the following reply
Hi Diane
Sorry that you are having problems with this.
I have checked the database and your subscription is set up fine.
I will add a note to your subscription to say that you haven’t received these. We do not have the stock of these to be able to send out but I will make a note to say that when we do get the stock we will send them out to you
Kind regards

I suppose I just have to wait and hope I get the next one or they get stock of the 2 I've missed. I won't hold my breath
