Very poor customer service, no follow up, no clear route to making contact with an actual member of staff, hiding behind a generic question page which masquerades as their customer support offering.
All because they know that unwitting customers are regularly shocked by the inordinately expensive add-on costs they see fit to throw at every transaction (and they do it very quietly too, so you might not even notice until you get to your receipt page, by which time it's too late to back out of the scam). By all means deal with them, but be prepared to be well and truly fleeced.
