You loaded credit and have since used them to pay for your plan and resources.

SO I DIDN'T KNOW THAT THEY CHARGED PER APP, BUT THE PROJECTS THAT WERE QUEDITITED ARE PAUSED DUE TO LACK OF LIMIT, AND THERE ARE ALSO SOME PROJECTS THAT I WANT TO DELETE, HOW DO I DO IT?

Please stop with the capital letters.

We do not charge per app, we charge for the usage (CPU, Mem, etc), and you used $10 worth of resources, and now your services have been stopped since you no longer have enough credits to cover running your services.

OK
