Yes, there are quite a lot of organisations where you need to speak to someone as you can't get a sensible answer by other means. So having inclusive 0845/0860 calls saves you worrying about calling them (as long call does not go over 1 hr.).
What annoys me is you unsuccessfully search their website for the required info and so dial the 0845 # shown there. The 1st thing you hear is "We are sorry we are very busy. Why not try our website
http://www.nousetomanorbeast.com for the info you need to save waiting?" and I'm thinking "I wouldn't be wasting my time phoning you if your website had the answer!".
BTW: All this is off-topic, but OP seems to have lost interest.
