Harrassing emailer

This person "*** Email address is removed for privacy ***" keeps sending me emails even tho I unsubscribed the company he represents over a hundred times. I've blocked him and the company but still receive their emails. I have emailed him and told him to stop sending the emails to me. I would write him or the company but the address is jumbled with numbers were letters should be and letters were numbers should be. I feel he is harassing me and there's nothing else on Outlook to do to him and his company. Please stop him and this company.
