Reporting abuse

I have sent 5 abuse reports for http://www.bankofafrica-ghana.com to support@ and info@ zohocorp.com but I have not had a response and the email facility is still active. My report did give evidence of the abuse.

I now want to report http://www.fnb-servicesonline.com

It is also being used for its email facility in a 419 scam

How can I get these email facilities suspended?

I am an administrator of aa419.org

Your help would really be appreciated.
Thanks
Lance
