I've had issue since Christmas.Went through support but they never fixed
it either so not sure what to do now.I presume as well as not being able
to add any cards you also get the Account disabled message when trying
checking out though website?
Did you ever manage to get this sorted? I have similar message when I
try to buy something but can't get it fixed (even with changing payment
method).They even gave me $10 free credit that I now can't use!
