Why can't I log in on Minecraft?

I'm trying to change my skin, but Minecraft is saying that I don't have an account with them EVEN THOUGH I bought one of those cards from Target four months ago.

Your suppose to but one and you own the account for life. Not "buy the account every four months"

I do have Majong account that I entered the code on, like I was told too and now I'm having problems.

Try signing into https://account.mojang.com/....com/login
If that works, go to https://minecraft.net/....net/login and sign in there with EXACTLY the same credentials.

If that doesn't work, you need to contact Mojang Support. There's probably some kind of internal error on their end
