42F dating 34M whose blowing up my phone

So this afternoon I received a call from the guy I'm dating but was currently in a no service area. When I reached service it popped up miss call so I responded with, "I'm going in and out of service, so text me what it is you need to say". He responded with "there is nothing to say I was just calling". So I said "ok im heading home & going back to bed". Ok harmless right. Well I was heading home because I really didn't feel good due to severe sunburns and wanted to get home, treat the burns, and go to sleep. Keep in mind he has zero clue I got bad sunburns as it's been several days since I had even spoken to him, due to "him working". Anywho, I finally get home and fall asleep. When I wake up, I have 6 missed calls from him and a message saying "Heeeellllloooooo? Are you going to fucking answer?" All 6 calls were made within a few minutes. Oh and lets not forget, he called my sister (after call #1 to me) when I wouldn't answer. Just tell her he couldn't reach me, because he just wanted to talk to me and it not an emergency. Of course at this moment I'm furious. I have never had someone I dated be this soooo wtf. Any advice on how to handle this would be nice?
