Cornerstone - an absolute nightmare!!!

I've tried over countless times to get hold of someone at Cornerstone to enquire about the PGCE online course before registration closes. When someone FINALLY answered the phone, they provided me with an email address. I immediately emailed the person and have still had no response. I've even been onto the Cornerstone website and tried to send an enquiry but even that doesn't go through.

For an institution that caters to online students, this is an absolute disgrace!!!! How would you like us to register if we can enquire about anything or get support!!!!!!!!!
