Their terms and conditions cover this upfront - they don't refund a cent.

In my case, I cancelled even before they delivered the first draft (of crap) - they threatened to charge me €65 or 75 as a cancellation fee, at first.

Today they've just confirmed that their cancellation fee is €100 - I paid nearly €300, sadly - and am now losing 33% of my payment. I hope all of our responses on this site save some other poor souls!
