Bug Where's the donate to leet servers app...

#1
My friend wanted to donate to my server using the "Leet.cc DONATIONS (NOT SERVERS)" app.
It says when he clicks a amount "This order cannot be found". (This message is from Google play directly)
I checked the app store, and the app is even gone from it. So... how can people donate with no app? Is it now a website? Or did LEET remove it all together?
Please answer im poor and can't get my own credits XD XD :p

BTW i didnt know what thread this was suppost 2 go in
