I didn't use my Payza account for almost 3 years now, I just decided to use my money today.
I don't remember I received or acknowledged any notification about ceasing this service so far.
Any ways, money stays money, and it always belongs to its owner, even if they decided to cease the prepaid card service, they should at least provide a way to allow the fund owners to recover their money.
So for me, if they don't any recovery tool, this be a confirmed scam.
