Zen Mobile Payments Down?

EIsea - Lost City

I have been trying to purchase zen via. my mobile phone yesterday / today and for each one (when using either of the 3 payment options available - Zong, Boku or All Pass) after I have sent the text it gets stuck on the "processing" step - which usually only takes a few seconds.

Is the mobile payments on the site down or is it just my phone network (Orange - UK) ? =/
