Netzero Email Abuse

Could someone from Netzeros email abuse team contact me?

Your spam notification system is spamming me and I have been unable to get ahold of anyone regarding this. 

Over the last 48 hours it has sent probably 25-30 emails to our abuse email address. All emails are the same, with the same content, and are actually a human generated email from a customer I personally know (Eg not even spam).
