The technical support phone number is 0113 350 3335 - I've called 3 times since Friday and been told it will be fixed 'soon'.
I spoke to them about this on Friday morning (UK time) and was told it was being worked on and would be fixed 'soon'. I asked whether that meant it would be fixed that day and was told 'certainly'. As of this moment (7:30am Monday) it is still not working. Not really good enough.
