Credit gone while buying more

[kuuldor]

I just want to read the bootload code but it says my credit is not enough. I have 3 left and 4 is needed.
So I bought 1 credit then it still says I have 3. I bought another 1 credit now it says I have only 2.
I think there is something wrong but I am eager to unlock my bootloader. So I bought 4 credit and now I have no credit at all.

Where did my credits go?
