Share 'Opening a PO Box in the UK - aaargh!'

I was sent from pillar to post, from post office to sorting office, and now it turns out I have to get the form from the website. It said the other week that I could pay for the PO Box monthly by direct debit, and I have the form for it, but now all mention of the monthly rate is gone from the website. Does anyone here pay monthly for a PO box?
