Just got my card. It says that its linked to ur plat cc for additional charges ie. Guest.
just logged into my account and it seems tht it IS linked to ur cc, and they have a diff sign in page too bec. on the screen shot it says about changing ur payment details but there is no link to click to actually change it so IMHO when u cancel ur cc they see tht there is no cc on ur PP acount and hence cancel tht too
Guess we'll cancel the card and see!!
