Way back then, payza used to be a good payment processor that is used worldwide, whnenthey were still having the name as alertpay, they were good, but all things changed as they sold it out to payza, now they are having a strict rules.
Not only even their strict rules. I think majority of their users can easily keep to their rules but the much annoying one is the way their value is going down. With this step they are taking, Payza may most likely be kicked off the way by the not so popular payment processors.
