This was a very interesting read. Quoting:

May have stumbled on something about C&B. There might actually be a specific reason why some financial institutions are rejecting them, just haven't been able to get further details as it looks like the site I was in just hit a maintenance window while I was on it.

Click&Buy is stating they are authorised and regulated by the FSA UK:

ClickandBuy International Limited is authorised and regulated by the Financial Services Authority in the United Kingdom. (Register Number: 454127)

So out of curiosity I went to pull up their reports on them, but can't get any real info on them just yet as it looks like they've started stopping some webapps for maintenance or something while I was browsing. This particular one went offline just after I pulled it up, but the first page from my search was still in my cached pages so I was able to grab at least their basic info:

Clicked the e-money link and that's when pages started coming up as unavailable. Guess I hit it right when they were taking things down.

Interesting that their basic info states they are not authorised. Which is a little concerning as they are still claiming on their site that they are authorised.

When you go to the FSA's detail on status entries, it simply states

No longer authorised
A firm is no longer allowed to carry out certain types of business that we regulate.

Which makes me even more curious about just what they are no longer authorized to do, and why. Wish I could get at the reports to get more info.
Now that's even more dodgy!

(PS edit: Yes, links in there are broken, but the link to the page I'm quoting should work - you can get to them from there.)
