In your case it was defined by the administrator. Did you check the block list as suggested?

What have you done to investigate the issue?

Respectfully, that is what you can expect to say to someone you are paying to fix the problem because you reward them for their time spent on the issue, and they can accept vague statements.  The more vague the more time it takes, but they are happy with that arrangement because you are paying.

The community is here to help you help yourself.  Not to outright "fix" things for you.
