I have had similar problems - was in the process of ordering a magazine subscription for my husband and when I clicked the Confirm Payment button the screen froze so I had to shut it down. I checked my Order History and there was nothing in it - there still isnt. Then when my bank statement arrived I noticed that they had taken the money yet I have received no magazine.
I have phoned, left messages, emailed etc. to no avail. Then when I phoned today I got the usual voicemail PLUS an additional message from eircom saying that their voice mailbox is full, hence I cannot leav any more messages. It is clearly not being checked anymore because they couldn't give a damn about thier customers. There's a far more simple phrase for what they do and it's called STEALING.
I have reported them to consumer connect and am awaiting a response.
