Elastic IP suddenly retrieve "This request has been administratively disabled."

I have had my account working for more than 3 months, Yesterday I kept doing the same things, and suddenly all the operations related to Elastic IP stopped working. Allocate, Release, Associate, Disassociate, and retrieve the following error: "This request has been administratively disabled."

I have been paying users for 3 months, and still, AWS customer support doesn't help me, and they forwarded me here. Does anyone know what I could do? I reset my AWS credentials, I used my root account, I tried even to use the AWS console from the website, and keep receiving the same problem.
