Buying z8 points with clickandbuy?

So it's been 3 days (that i've been trying) and I still can't purchase z8 points through clickandbuy or boku. Whenever I finish filling my info on the clickandbuy, it begins to finalize the purchase but then a red bar comes across the top and says "This payment method is currently unavailable." Like, do yall not want my money? Seems pretty stupid to me considering that the payment is 100% going to come through... Boku says that my phone isn't accepted as well. Anyone else have this issue?
