Well I apologize if I misunderstood your original post as it appeared to me you were defending ClickandBuy with an argument of that since their website says you won't be charged with or without cancellation that they are credulous. My point to you still remains though: regardless of what their website says and whether or not you even have proof of cancellation: they still can(and have) abuse your information and with a slew of "beware: scam" flags posted all over the internet and a persistant F rating from the BBB I do not trust them.
Also: only the first couple lines of my post were in response to you, the rest was just general information I was posting.
