Need some info on Donation , please help.

So I was donating with Payment Wall, the thing happened was its holding my payment for hell so long, but in the end I got it, took a good whole week, so thats that. Therefore I tried to use Super Rewards, and it works well for me coz the credit come in less than an hour. Today when I try to donate again, the "Buy Gamezaion Credit" section, where u select amounts etc, just disappeared.......Can anyone tell me why?

btw i tried to contact Super Reward, no hella answer was replied.

And also, if theres any other way to donate to gamezaion, please tell me.....like the one where u donate straight through PayPal was nice, but I donno why they removed it.
