Can't import repo from Git and Can't delete the undone repo on Bitbucket

I tried to import the 2 repo from my Github account and they both failed. Now I want to delete the 2 repos and redo the import but I can't find a way to do so. I hope someone can help me with this issue. The 2 repos' name are android_kernel_samsung_aries and android_kernel_samsung_aries_OLD

With this 2 code:
