This man keeps on calling me everyday and i don't know what to do.

Call Blocker
You need to buy a standalone call blocker, call blocking phone, use your carrier’s call blocker if they offer one, or download a free call blocking app for smart phones.  For conventional cell phones, assign the number a letter like “z” and make no ring.  You may also need to have your carrier increase the ring time to avoid having them leave a message on your voice mail.
