I am unable to unsubscribe from all newsletters, I’m getting spammed !

As above, the unsubscribe system is not working.

Before I put in a domain wide block for our 100,000 users, would somebody from Tech Republic or CBSi like to remove me manually please?

I have tried multiple times but the unsubscribe system is clearly broken.

The newsletter/spam is being sent to my registered email address.

thanks
